I was doing some surfing for no particular reason and randomly clicked on PSP's website. I know it doesn't apply to most of us, being that we photograph for fun, but I thought I would pass it on. I know our commercial list members are well versed on these rules as they apply (as well as the airlines' reimbursement). This is the first time I've seen it in writing up front on a website and thought I would pass it on in case someone gets questioned at this or any other airport. Walter DCA
