Sorry to hear that you live in Boise.
I ended up going to the show in SF because a friend had an extra ticket. I'm not really a fan of the folk/pirate/whatever thing but for everything I heard about Alestorm, I wasn't particularly impressed. It didn't help that it was about as late as a headliner could play in the state of California, but I thought Trollfest was way more entertaining. Took me about 2 times through the chorus to realize that they were playing Britney Spears' Toxic.
