The bottom line here is that no matter what size your wheels are, if you are going to ride someone else's trails you need to show some respect to the people building it all. Offer to help build before you ride, or during your session, especially if you go often.

If you case, bail or in any other way screw up or put ruts in a lip/lander, then you need to fix it, or tell someone that knows where the tools are at so they can help you fix it.

You also never tear down anyone else's jumps, nor do you change the lips angles just because you can't hit a jump, because i assure you someone can ride that jump just fine.

And finally, you never ride wet trails.
