I don't know what happened with my YouTube feed but all of a sudden every other video in my suggested feed is about propane, mainly filling the little 1lb bottles from a larger tank. I didn't do a search or even watch a video with/about propane. Maybe I thought about it after reading a resent PUP post, but that was on my work desktop and the YouTube feed is on my iPhone. The two are not linked in anyway. These things scare me sometimes.
