Seems like we've got a few blues fans on board.  Since I've started playing again I've gone back to my roots and have been hitting a few of the local open mike blues jams.  Lots of great players in the greater Boston area.  Most all the jams are "no cover"  Here's a pretty current link to the local jams.  If anyone wants any more info. (jimmy & prof. drag out those Gibby's!)  feel free to drop me an email @ gundog45@msn   1st guy to show gets info. on a couple of Haba "hotspots" and an invite on the "Sokinwet" for nxt. season!
