A good friend rode shotgun over 1500 miles on my move from Ohio to Arizona. Before catching the plane back he was fed well and did some sight seeing. He is a veteran and has quite a good knowledge of camping and the outdoors in general. He pointed out a few important things along the way and I learned a lot. On one of our local trips my wife had to hit the mall and go to Sephora "Yuck no" but we were going to eat afterward so we saw other things in the mall. I stepped into crate and barrel and grabbed a couple of silicone funnels. My friend asked me what they were for as i gave him one, The look on his face was kind of skewed. I explained, this could save your life. Put it in your go bag. It collapses small. It can be used to fill a water bottle from a very shallow source. It can Also handle a little heat so using it as a handle could serve the purpose. It can be pinched off to stop the flow in order not to waste precious liquids wen filling a small flask. The twisted face turned into a light bulb.
So, while Crate and Barrel is not a place I normally go, I saw these while being dragged through there once, remembering where you saw something that could come in handy is never a bad idea.
