Who else read "Water vapor from the pilot’s breath and sweat condenses on the cold metal sphere and drains to a space where it’s sucked into a plastic bag. In an emergency, the pilot can drink it." and immediately thought about stillsuits on Dune?
I went to South City Lumber to pick up some "flavor savers" for my gas grill. The person who helped me knew what he was talking about and even though I hadn't been able to find the model number for my grill, we were able to find the exact bars that I needed.
I've stopped by a bunch of other times when I've needed various other hardware items and always been able to get help finding what I needed.
