XM has a good one too. In my house, there is no escape from the twang of a banjo, lol! We have Merlefest in my hometown of Wilkesboro, NC.
Oh, and I LOVE Ricky Skaggs! I bet that was an awesome concert.
Mac, like the C-130 in your avatar...my husband was in Aeromed Evac before he became an officer. He pretty much lived on a C-130, lol.
