Ahh, sun. It is the second jacketless day for me, and it is lurvely. But if skeptical you remains unconvinced that spring really, truly has sprung, here's another sign: Tickets for the annual Green City Market chefs' barbecue are on sale now.

The alfresco event at the south end of Lincoln Park has grown immensely since its inception 11 years ago. Tickets back then were something like 25 bucks. Now, they're $100, and there are crowds. But there also is really delicious food and ample opportunities for chef-spotting, if you're into that sort of thing.

The barbecue is from 5:30 to 8 p.m. July 21. Tickets are on sale at brownpapertickets.com and at the market itself, which runs Wednesdays and Saturdays. (For our full guide to area farmers markets, click here.) Worth noting: Tickets won't be sold at the door.
