So I am going on vacation skiing out in Utah next week. I plan on taking my digital and film camera. I didn't think anything about transporting the film till this morning when i saw a film safe x ray bag on craigslist today. Will I need one of these bags to transport my film? How do you bring your film when you travel? Can i just put the film in my pockets when i go through the metal detectors and show them that I have it and don't want to ruin it? Any other things that might hurt the film that I don't know about like temperature ect? I am new to using film. Thanks for the help.
