I've been going to Market for years now. I hit it up every time I can. It's a very cool chill environment of local artists and activists who are out to share their passions.
The music is always great. The people are all very friendly and accepting. You may feel out of place if you're dressed up, but seriously, no one cares.
My favorite part of it is the photo booth. There's always a really cool theme and $5 gets you a really fun great quality photo, although you don't have to buy it if you're broke. It's just fun to do.
You can pick up lots of different things from awesome clothes, paintings, I got a belt once that rocks my world, photos, jewellery, and music stuff.
Not to mention, you're supporting local artists and contributing to the community. Angela's done a wicked job with it.
Volunteer if you can.
