Ok Guys
From the sublime to the ridiculous.
I've been using the mobile phone method for a while with some decent results.
On the occasion when you see Mr Fox,but he's in the wrong place for a shot,how about this.
A small electric radio controlled car (silent), with a furry toy or rabbit skin on it, when Mr Fox appears in the wrong place, drive the (rabbit car)
to the correct place and there you go, the shot is on.
I did say ridiculous, but who is brave enough to say it didn't work
Happy rallying
Alan
