I was out walking around a local lake yesterday and noticed this for the first time.
This is at one of a couple of spots along the shore, where some old gents periodically arrive on their electric bikes and settle in for a day of fishing. I suspect it’s mostly a social thing, and they seem to enjoy it immensely.
When I noticed this yesterday, I wondered if these floats belong to different people, or is it just one slow learner 😉 Clearly the alder tree is in the wrong spot.
