This is all hearsay (from reading on these type of boards) so someone please correct me if it's wrong, but I read a couple of stories of samples getting rejected at 93 degrees, People say hand-warmers work, but since it's almost thursday morning, guess you'd have to get them at a Walmart or sporting-goods store, and then I guess you'd need to practice,,,,would be good if you could postpone till tomorrow. Hope you do ok.
