Summer Folk Fests

Outside of the regular folk fest, here are a couple of options that would go great with a climbing trip

Butte - Nice granite climbing just east of town on the King

Libby - Stonehill climbing

Helena - lots of great climbing all over

Fernie - maybe the locals will fess up about some of their developments.  If not, lodgpole road has lots of new route potential.

The Butte festival is by far the best.  The Libby one has a nice relaxed vibe.
