welcome! snail trails rides have slowed down a bit but there'll definitely be more this year. i'd find the following threads and subscribe to them so you can get an email the moment a new ride is posted:

Snail trail rides in southeast qld for 2012
the dirty rides are dirt rides, not adventure rides.they are usually in glasshouse mountains and no prob on an XR650 if you are an experienced rider.
