My great new idea:

I'm going to visit EVERY BAR IN THE CITY.

I already have some ideas - I'll make per-neighborhood maps for every neighborhood in the city limits, and count as bars everything that's a bar or a restaurant with a bar where you can go in and sit down and order a drink there and not feel funny. I won't count venues that serve liquor but you have to get a ticket to get in (e.g. concert halls, or airports).

I've notified some friends and they're already psyched.
