Aha well seeing as we have no current reports on San Antonio here is some stuff you might like.

Yup there is a session in SA - location unknown at this time but is well attended and has a great crowd of fiddlers and other things.

The Autoharp/Dulcimer crowd tend towards the small town Fredricksburg - which incidently has the best homebrew beer I have tasted in years! That said I am probably missing tons of things as the metro is so vast. I went to one Boogrog session in a a Bar and it was fun but they had no jam, later some folks said we should return next week but city life and distractions - oh well.
