Hey I stumbled upon this site and thought some of you might like to check it out.
Its basically a list of events that you can select by region or theme

http://www.whatsonwhen.com

There is some really weird stuff out there. I've heard of bog snorkelling but not bog mountain biking!

Yeah, this is a great site and it's been listed on the homepage of Tpunk for a while now.

Thanks Z B) !
