If you happen to be around during their concert season (Oct-Apr), check out the Magic Valley Symphony (Twinn Falls) for an enjoyable evening of music.
And of course make sure to say hello to the Timpanist (that's me!)
Clothing/Shoes/Weather Gear: In the summer you should definitely bring along your standard summer gear. Buhl gets quite warm in the summer (not quite like Phoenix) but it's generally not very humid so even the high heat is still bareable. In the winter definitely bring along a nice warm winter coat.
