This is an extremely late reply . . .
(and as far as I know, no local game stores are open for play right now anyway)
I just moved to the Riverside area and will be looking for a Battletech Group when things re-open :D
I've been playing for a few years and am versed in Classic, Alpha Strike, and even a little A Time Of War.
I really miss playing pick-up games.
Fellow Inland Empire players are ideal, but I'm willing to drive an hour or two away now and then. (I did that for my last group back East)
