I ride out in country gravel roads in the Midwest, so have found my share of beer cans...sometimes unopened. Once found a Yeti aluminum beverage can “coozie”, still new in the wrapper...definitely the most substantial keeper.

I also run, in the city, mostly in the wee hours of the morning, and have found more substantial things. On several occasions I have found credit cards, drivers licenses, and other wallet items...once including the wallet itself. I usually run to the address and drop it in the mailbox, unless the area is sketchy or the drivers license photo looks particularly “methy” in which case I take it to the police.

Pro tip: stuff falls out of the back of trucks when they cross railroad tracks at high speed. I almost netted a decent angle grinder near our big RR crossing, but decided to leave it and come back after my run...long gone by then.
