I found out on gwerdy some time ago I have probably walked past one well known clicker a lot of times but never knew it.
I have knew the founder of Genix (Jon) since about 1996/97, he is my best friends brother. He did this demonstration for the click convention, and has had the misfortune of meeting that certain gurning dr pepper drinking individual .
I have been in and around Norfolk (I seem to remember a museum or something in Thetford I think it was called, and being around Horsey) a few times but my home town is Birmingham, although I am hardly there these days.
I always thought a click convention around the Midlands would be good, but they always seem to host them down by London.
Oh I remember two museums around Norfolk, a war museum with a big 6 wheel drive thing they drive you around in (back breaking experience) and a vintage fair type museum with merry go rounds and old fashioned organs. I can not remember which one was at Thetford.
If Phizzy's Youtube channel is legit, I used to work close to his home town (I used to work in Lichfield).
There used to be a few Australian clickers, but they are no longer active - Ashman, Muggus, and Buster. I seem to remember Shadowcaster being an Australian too.
I live in Pearl Illinois in Pike County, but to be truthful, if I one day got a email saying something like "OMG! I LIVE RIGHT NEXT TO YOU! WE SHOULD MEET!" I probably wouldn't do it for several reasons...
