We attended the Barksdale AF Base Defenders of Freedom Air Show a week ago yesterday and I stayed in the B in the parking section reserved for RV's and other oversized vehicles.
It was windy and sunny and hot. I enjoyed the comforts of home and had prime viewing of the show and could observe jets/planes approach the runway in front of the stands.
Four Thunderbirds (F-16's) screaming by in formation right over the van took my breath away. It was freakin' awesome! Incidentally, our daughter flew a T-38 into Shreveport doing a cross country check ride a few years ago, that was cool too.
I was told by an airman I could stay in the RT but couldn't mill around outside. I almost posted about the experience from the parking lot but didn't so I'm glad to share how an RV can make this experience so very very nice.
I hope this opportunity works out for you and you have a wonderful time.
