Pro tip: the guy at the recycling drop off in Boise taught me more about plastic numbers in 10 minutes than a whole webinar did | Climate Action - nhfree.com
Learned more about batteries from a guy at the auto parts store than I ever did from YouTube. He popped open an old car battery and showed me the plates inside, explained why cold cranking amps matter more in winter, all that stuff. Spent like 20 minutes just talking to me in the parking lot. Same deal with the guy who fixed my lawnmower, dude knew carburetors inside and out and showed me how to clean one right there on his workbench. Some people just know their trade cold and love passing it on. Those ten minute chats beat any class I ever sat through.
