I have lived in Boston for a few months a long time ago when i was not yet geocaching so i currently don't have any cache in the area. I used to be a consultant to a MIT spinoff.
I'm back in Boston for conferences, will arrive late on Sunday and start working early on Tuesday so why not going back to MIT to buy a t-shirt and some books and of course meet some geocachers.
I propose to meet at 5PM at the entrance (outside) of COOP until 5:30PM (official event time) then we can go for a beer or two. I'll be in jet lag so two beers will be the max for me but feel free to order more.
If i don't forget them, i'll have several travel bugs to discover or exchange.
The closest "T" station is Kendall (red line), across the street.
