The annual AltWheels festival, held in Brookline, Massachusetts, is just around the corner. AltWheels is a chance to get some hands-on time with a wide variety of alternative and sustainable transportation ideas, from advanced bikes to hydrogen cars to solar vehicles. I gave a heads-up last year, and reader Jeff Egnaczyk posted a link to his photos of the event. This year, I'd love to hear from more of you who attended. In particular, I'd like to know: what struck you as realistic? What seemed implausible or ill-founded? What surprised you? What gave you a "I'd really like to see *that* on the road" feeling?

AltWheels 2005 will be held Saturday and Sunday, September 17 and 18, at the Larz Anderson Auto Museum. Directions and (inexpensive) pricing info can be found here.
