They run an informal Euro Bike Night every Thursday. People start collecting there probably 6 or so. The store closes at 8 and many of the crowd rides down to the "Miracle of Science" bar and grill in Cambridge where some eat (great burgers) and some don't. Most people drift off from there, but some single people with no responsibilities (and maybe married people with struggling relationships) head to Newbury street for ice cream about midnight.
It starts out as a nice way to meet people. Many of the CD-ROM listers show up. Some form DML as well. It tends to look a bit mor poseur-ish once it heads into town. I'll be in full leather (I don't want to admit to the speeds we were ripping down Rt 2 last time I went). Hanging around a bar in full leather is about as poseur as it gets.
I'm going to make an effort to be there next week. If you think the route speaks for itself consider adding to the thread "Best Roads In New England" If there are enough responses I'd going to try and get a new section of the site added for rides.
