On Wednesday me and my girlfriend are flying to Denver and we will be camping out of our backpacks for the first time and we will be staying at about 10,500 feet in the Rocky Mountain National Forest. I bought a big duffel bag for my backpack so the airport luggage handlers don't rip the straps off of it and I took the fuel out of my stove and will buy some there. I have a Kershaw OSO Sweet knife in the checked bag so I guess that's OK, and my girlfriend wanted me to take a gun since we're in bear country but I've heard it's a big hassle at the Denver Airport and you need figure an extra hour or two to be taken with an armed guard to a special Xray machine, so no gun on this trip. I am required to have a commercial hard sided Bear-proof food container which I bought for $75 bucks. The weather forecast calls for a chance of rain and the high will be 65 and low will be 47 degrees and I think we're prepare for everything I just haven't flown with a backpack before, anyone have any experience flying with a camping backpack?
