A good place to start would be the forum called New Hunts and Rumors.
I'm seeking info on some new online or armchair hunts for my group. Is there anywhere that posts UPCOMING hunt info??? Appreciate any and all info!
"We may not be first, but at least we are not last!" Meaner Simikkles RULE!
There's also a new twitter account set up for just this reason. It's just started over in England, but the idea is for it to announce all upcoming armchair hunts worldwide. If you follow ...... @treasure_club ...... you should get the tweets.
If you know of a hunt that's about to start let 'em know on their facebook page ...... The Armchair Treasure Hunt Club | Facebook
Hopefully this should flag stuff for us all.
