Thanks for the reminder of the thrill it is to do errand-y things by bike for the first time! It's become kinda old-hat for me, and it's easy to forget how fun and empowering it is to leave the car behind....

My favorite annual errand to do by bike: renewing my car's registration, down at the county clerks office. There's no way I'll ever drive there again-- the free parking is in a garage that looks like it's about to fall down, and it's less than 2 miles from my home. Showing up for jury duty in December by bike was awesome too, and brought on a lot of interesting reactions.

I find that grocery shopping on the bike can help cut down on impulse buys. Even with both panniers and bungees for attaching stuff to the rack, there's still limited space.
