If you've never gone to Twilight before (the bike races downtown) then please go check it out! It's one of my favorite times downtown. It's an all day event with a shit load of stuff to do everywhere. The races usually start around 4 or so (double check that), there's booze sold on the sidewalks, food everywhere, and it's just an all around good time!
I've been at every Twilight for the past 5 years and this is the first one that I'm missing. I have mixed feelings about this, but I also know I get to avoid the people who drink for 10+ hours and then want to fight everyone within arms reach of them, so for that I'm thankful. For example, the guy who headbutted me 4 years ago and broke my nose. I wasn't excited about that one.
But seriously, go check it out.
