Re: 2008 Boston Regional
The Boston Regional has been great since it began in 2006, but I think this year really set a new standard for showcasing FIRST at a regional event. It was officially the most attended regional in...

Re: pic: 121 Thermal Imaging
That's really cool...not literally, but you know what I mean. I like how the Victors never, ever get hot. They can take so much abuse.
You guys looked great at Quincy. Good luck!
