My neighbor told me that used bikes are selling for mad money. He tried to order a new Trek road bike, and the dealer said that orders are backed up over a year. Same with cars. I was looking at Porsche Caymans, and there were 4 available in the entire US.
I disagree with drawing a straight line from COVID support checks to supply line problems. I think the pandemic is still playing a big part in this. Everyone is working from home, they look around and decide they need new shit or more shit. Heck, I bought 3 new pins this year, and I usually only buy 1.
