had to pull the old "what about the 5th saturday(this saturday)" on me didn't you? turns out there aren't anymore months with a 5th saturday other than May... and August...... and November, and sometimes December, and March... but never February... last year there was June and September. There's almost always 4 Saturdays in every month so the printed posters and advertisments are a lttle clearer than, than this post.
you actually have to show up on one of the saturdays be it the 1st, 2nd, 3rd or 4th to start a lobby for "5th Saturday" jams... not naming any names, but the initials are ChefMenteur, plus as it turns out there aren't enough bluegrass/old timey songs in existence for a 5th Saturday... yet.

so Reno's has Gospel Bluegrass on the 1st Saturday, and straight up bluegrass the 3rd Saturday and Bynum has it(bluegrass) now on the 4th(last saturday, where were you?) and the 2nd Saturday... that would be June 14th. Sooner or later you'll have to dip a toe in the water if you are ever gonna get your feet wet
