Hi - as a scientist who's a mom, my fun time is generally schlepping the kids to soccer, lessons, etc., and then helping with homework, making dinner, etc. However, I bike-commute, and the weather's been beautiful (except for today's wind), and riding to and from work with the sun and the beautiful colors in the foliage has just been spectacular. I like to ride in the snow in the winter, because it's a challenge and fun, too... Sometimes I'll take a 1/2-day and ski, or take an extra-long route to work just to play a bit; I like to play piano (my daughter sings, so accompanying her as she practices is pretty fun, too).
