Thanks everyone for the feedback, especially Dean and oneofthose. Mexico here I come!!!
oh, but a quick follow up to satisfy pure FTer curiosity - mostly for Dean or oneofthose:
So the quantity limit on "personal items" relates to a single can size, like 18oz? Does that mean there is no overall limit? Pack as many aerosols as you want, as long as they are all personal items and under 18oz for each bottle? I'm not doing this, just curious now.
