That's great. I'm in Norwalk Cove with few CSR friends. If you'd like, send me personal message and we can exchange personal info (email, cell, etc) to make it easier to communicate.
Yachta Relax, we have quite a few people in LIS area who's getting together pretty much every weekend. Feel free to join us. How far are you from Norwalk?
