Park Slope is a funny place. It’s a neighborhood you move to when you’re ready to raise kids–just not necessarily ready to grow up. Hence we get strollers in bars, fathers who wear Ministry T-shirts, and Michael The Lemonade Guy. He’s 40, and he has a lemonade stand. A very nice lemonade stand, mind you, but a lemonade stand nonetheless, with plastic cups and Rice Krispie Treats and seriously confused neighbors. Curiosity got the best of me, and so we have this: Sidewalk Entrepreneurs Grow Up.
