I'm glad I found this thread with the list of frequencies. I am planning on bringing a scanner with me to monitor radio traffic this year. Last year I used the liveatc app on my iPhone. The only problem with this is that the radio traffic is delayed some, so when you are hearing ATC tell an aircraft to "rock your wings," they are already rolling out on the runway. A little hard to stay with things if you are watching live. Not a bad app to have if you are just hanging out at your campsite though.
