Thanks for all of the advice, it is appreciated. I just went out for almost 30 minutes and rode back and forth in my apartment's parking lot. I don't have the time to go somewhere else and get to spinning class tonight - especially with needing to take the front wheel off the bike so I can get it into my trunk. And out, and back again

However - and this is a big deal for this total cycling novice I "played" for 20-25 minutes and did not fall over once! Indeed, I didn't come close to it. A little wobbly, yes, but I didn't fall over! Now I need to find a larger parking lot (with no traffic) where I can really play!
