A (hopefully) sunny day in the park, vintage and artisan pieces from 50 of Indie Mart's local vendors, DIY terrarium-making classes by Workshop, adorable dogs up for adoption, and tons of delicious gourmet grub courtesy of Off The Grid—that's precisely what's going down at the 28th Annual Alamo Square Flea Market this Saturday. Plus: Lots of pretty pastel houses (!!), and it's totally free with many of the profits from the activities going to local charities. Be there or be, er, square. And get more info here!
