Went through the freezer to see what I had and found some 8x10 PW Ultrafine I had bought during the great Ilford scarcity of awhile back. The stuff was cut from the end rolls of FP-4 and was packaged by Photo Warehouse not in 3-piece film boxes but rather cardboard envelopes like small quantities of enlarging paper.

I want to take a flight next month to Gunnison, CO and I'm wondering if film in an envelope (about the size and thickness of a magazine) would be less suspicious than film in a box to the TSA blokes?

Any thoughts?
