Grockle is a SW England term for a tourist (mainly by people who have only
lived in Devon for 5 minutes!) In Cornwall they are Emmets.

Ha ha ha! True! Though I must admit that I got the saying from a work
colleague who has been living here all his life.

The term "Grockles" comes from a film which was set in Torquay in the 60s,
or so I was told (could be an urban myth, plenty of them around here).

Currently at 12:00, 20.8C, RH 56%, DP 11.6C, Wind 3.5 mph WNW, 1031.3 (R).
