I don't want to step on any toes here so if this does, feel free to delete it.
There is a new forum for off-roading. Dirt bike, quad, snowmobile, 4x4. All of it is allowed.
Ground Pounderz - http://www.groundpounderz.org
It's brand new, so not a real busy place yet. It's growing though. If you are into dirt riding also, check it out.
Oh, and feel free to comment on it (good or bad). No offense will be taken. It's not for everyone, and I'm sure some people will be like 'why another forum'. If this is you, that is cool, no need to sign up.
Cheers, hope to see some of you contributing.
