I was thinking the same thing last night when i went to my local "spirit"/b&m. I always buy those pillows when im there but they are pretty useless without some "distilled" water ! So next time, ill either bring a pre-wet pillow with me or carry a small cooler with beads It gets very hot here in Texas and you never know if your going to need to stop off somewhere else before you can get home (i live pretty far from the spirit store)
