Yeah it interesting to hear other people's experiences, some of my friends in the Midlands find the lengths I go to very amusing, as they have greys running around there feet in public parks. The woods I shoot are all private and pretty much the only people who come to them are shooters from our local syndicate or poachers. The woods get shot fairly regularly with shotguns by pigeon shooters. Squirrels are such fast learners, they see a person here and they bolt.
Edit - I shot one yesterday, and saw another, both late afternoon. Bumped into one of my friends at dusk, similarly he's finding they are more active in the late afternoon at the mo.
