Hello Rick, definitely lack of interest at the moment as we can't go anywhere lol! You may be surprised though, the ukgpa site had a lot of members for purely gold panning.
It makes for a good weekend away and a bit of an adventure too if you turn it into a camping trip!
But yes, you should definitely give it a try if you are ever offered the opportunity. It's great fun, although it's surprisingly more hard work than you may think!
Hopefully someone may come across this thread and update whether the group still exists.
