Before I know anything

This morning I open the fridge to find breakfast and there in front of me are about 7 liters of fresh lemon juice, the juice of 98 lemons. This summer, lemon juice is my holy water, my cobra, my savior...well, at least that's what I'm hoping.
Knowing that the year ahead of me is going to be intense, long and time consuming, I decided that the last thing I wanted was to spend the summer working, while the days passed by without me noticing. But as is the case with most everyone, I also knew that I was going to have to make some money, if not for saving then at least for living. And I knew that to fully appreciate the summer, I was definitely going to have to spend some good quality time at the beach. It occurred to me that with a little motivation, one or two sacrificial lambs and a bicycle I could make my summer exactly what I wanted and needed it to be. Really it just popped into my head: I could sell lemonade at the beach. And then it stuck, the idea didn't go away, and instead of applying for jobs I started figuring out the logistics of selling lemonade.
Wreck Beach is Vancouver's "clothing optional" beach with a culture of its own. It's right at the western-most tip of Vancouver, maybe the only beach that you can't see the city from. Not only is it out of the way, but it is at the bottom of a very long and steep flight of stairs.
It is also the only beach, that I've noticed anyways, where there are vendors selling everything from beer to burgers to sweet buns. And no one is selling lemonade...yet.
There are, as one might expect, a lot of things to figure out before going off and selling lemonade, let alone for a profit. I determined that as far as gear goes, I would need a bike trailer, cooler, cups, a juicer and since there is no source of fresh water at the beach, something to lug lemonade around in. I would need to source lemons (organic or traditional?). And I would need to figure out the best way to get everything down to the beach and how I would haul it around once I'm down there. Plus, I'm not a business woman, this will be my first attempt at as an entrepreneur. I'm just guessing my way through it.
As of today, this is my idea: I will pre-make 5 gallons of fresh-squeezed lemonade, bring a cooler of ice and a schwack of cups in my bike trailer (thank you, thank you, thank you, Michael!) and sell approximately 12 oz. of lemonade for $3 a cup, plus a $1 deposit on the cup (washable and reusable). My trailer has pretty big wheels and a handle, so I'm thinking I'll pay some strapping young lad (or lass) to help me carry the trailer down the stairs. If it is still too hard to maneuver the trailer on the sand with all that weight (I'm thinking somewhere between 70 and 90 lbs), then I'll find a hiding place to stash the big jug and use a small jug to walk around with. I'll definitely be a cruising vendor, as one needs a permit to stand still and sell things.
So far, I've invested about $89, and I still don't have a cooler. If I can sell out in a day, I'll make about $150. I'll have to replenish ice and lemons on a regular basis. My first case of lemons was traditionally grown, but I've promised myself that if I can actually make money doing this then I will switch to organic...about twice the price. And that's really the question, can I make money doing this? Can I even pull 100lbs on my bicycle?!
So for the rest of the summer I'll be updating this blog with stories and pictures of life on the beach, how much money I'm making, and possibly bragging about how wicked my tan is! But don't worry, I'll wear lots of sunscreen. The great and scary part of it all is that I just have no idea what it's going to be like. I am totally open to any suggestions anyone might have (yes, I have thought about spiking the lemonade, but that's illegal, and I don't really want to deal with the cops). In fact, please help! My goals are simple: make money, get strong and get a tan. This Sunday will be my first selling day, so wish me luck. I pray for good weather and generous patrons!
Oh, and feel free to come visit me on the beach, I'm selling delicious, ice-cold, fresh-squeezed lemonade.
