Going through IFS at Destin, we were completely surrounded by Warning areas, prohibited areas, restricted areas.. you name it. We had to do all of our north-south flying through a corridor, and it made me pretty nervous on my X-ctry solo flying with restriced airspace on either side of me.
I, for one enjoyed the experience. The airspace was always busy, both from military traffic from Hurlburt and Eglin, and from the ass-load of civil traffic coming and going from Destin. It really taught us to maintain a vigilant scan and always be very aware of what's going on on the radio.
My best memory from IFS was being shadowed (at a considerably greater distance than 20', mind you) by a F-22. We weren't in a restricted area, and I think the guy was just out having fun but he followed us for a few minutes and broke off back towards the Tyndall area. It was awesome. Musta liked flying slow... :spin_125:
