The 10th annual Baltimore EcoFest is this Saturday, April 27th in Druid Hill Park from 11:30AM to 5PM. Besides food and drinks (including a beer garden), you can do a free bike ride around the lake and pick up a free tree sapling. I've gotten two in the last two years including a dogwood tree that just bloomed this spring after being planted this time last year. Here's the website.
