Pissed off Master's student Kathleen Shafer has begun a new blog inspired by her recent experience with professional (not) TSA agents at San Francisco airport not properly acknowledging the existence of
medium large format sheet film. Check out the details here: http://tsaintgood.blogspot.com/
In TSA's defense, I've only had good experiences with all of the TSA agent's I've been screened by. The only problem I've experienced is with a pastry server that the agent thought was a pastry knife. It couldn't cut anything more tangible than a lemon chiffon pie, but it had to be confiscated since it was more than 4" in length.
But nothing film related has happened negatively for me.
