Thinking back to other Events linked to previous Megas, they were either outdoor or in a large pub - and that was crowded

I like the two outdoor suggestions:

Flash Splash Mob in Bourton (well I would wouldn't I ) &
the CITO on Burton Dassett Hills - is there a lot of litter there then?

Both could display the CacheWalker banner if we want to advertise ourselves.

Has anyone talked to the committee about any of this yet?

Not that I'm aware of.

I haven't,but don't forget my original post was for a stall/table at the mega event nothing about hosting events.

So it's you we should blame for these Events
