Real name: Terra
Where do you live? metro Boston
Explanation of your handle: Someone has always already taken the username "Terra" by the time I'm registering for a new forum these days, but I find "MsTerra" still works more often than not. In fact, Terra is a nickname that started out as a computer username in college 21 years ago.
Explanation of your avatar: haven't posted one yet - avatars are not my forte
Age (general or specific) early 40s
Occupation: administrative assistant at a well-known local engineering school
Favorite bike: not yet knowledgeable enough to say
What's in your stable? Specialized Sirrus hybrid - I think it's a good starter bike that can be a trusty commuter for a long time, but as I ride more and get better I'll be putting more thought into road bikes....
Fastest speed on a road bike? where? when? I've never had a speedometer/bike computer and will probably resist that trend for a while. I've already been accused of being a geek because I'm reading about cycling and looking at online cycling forums. 
Another picture of yourself or your ride? Not until my bum gets a little smaller....
What is the biggest lie you've ever told: I want to be just like you, R---....
Most memorable moment on my bike: Learning clipless pedals, the Arte Johnson phase. Seems to be a common memorable moment around here. (On the other hand, my rotten husband just started riding clipless today - a few minutes in a parking lot, and then we were off on a ride, and he didn't fall once. B@st*rd...)
Most fun ever had on a bike? When I was cycling a decade ago, I would get up early on Sunday mornings and go out on the local rail trail. It was less congested at those times and I could get up some good speed for nice stretches.

So look out for those beauties, oh yeah..."
