Hi,
I'm new to moutain biking and was looking for some tracks to ride in the Perth area and stumble across this web site.I have a couple of questions,
The tracks/trails listed on the site (Kalamunda circuit,Forsyths mill etc), can any body ride them or do you have to be part of a club/affiliation? What does joining the PMBC entail and can you clarify why I would need a MTBA lisence? Is it only club members that can participate in the group rides I've read about on the site? Thanks in advance?
