How do you transport your gear in these days? Andrews AFB in MD last week restricted any bag brought in over 1 cubic foot and absloutely no backpacks. One cubic foot doesn't hold much. NAS Pax River's airshow this weekend says camera bags are OK (no mention of size) but again absloutely no backpacks (sucks because I use a LowePro backpack). How are you non-media credentialed folks getting in your 100-400s and long primes in with a body?
