SBQ: Travelling Stitcher

Do you stitch “on the go?” (On the commute to and from work, during your lunch break, waiting for the kids, etc.) If so, do you have a specific “travel” project or do you just grab whatever you happen to be working on and take it with you?
Yes, I do. Some days I only stitch on the commute to and from work, like yesterday, when my evening was taken up trying to figure out the taxes. (The only time I figured my California taxes correctly was when I used Turbo Tax; they're impossible. And I'm not buying TT to figure out how much I owe for my one month of residence!)

I sometimes have a travel project and sometimes I take whatever I'm working on. I am a little reluctant to do the latter, however. Even though I'm pretty conscientious about keeping my things neat and clean, the bus and the subway are dirty. Eventually though, I did bring Souvenir on my commute because I just had to get it done! But I wouldn't bring large projects. You need to keep yourself kind of small when you stitch on public transportation.
