Sounds like a fairly good trip overall Matt..
Didn't see you mention they charged you for the over 50 lbs case thopugh (?)
My last checkpoint coming back from Michigan, the guy took my box of unexposed tri-x (4x5) and swabbed it, then came over to the table if could open the box anyway. I said I'd rather he not, but he did for a second and I saw the foil pack (which had been opened by me previosly) exposed for that brief time. I think it's more out of curiosity on their part than anything, but is still stupid. He said "sorry"..
I missed the perfect snow the day I left though..
Let us know if the claim works out.
