Well glad to see that you have a good attitude, Zippy. All duners are welcome on this site, except the ones who like to trash the dunes, disrespect the rules, etc of course. I agree it's one big sand box. No matter where you play you can have fun on this site, GD.com, wherever. Hell I haven't even BEEN to GD yet and I have been a member on GD.com for years. Hopefully that will change before the season is over though as I am hoping to make a trip down to G at the end of February.
As for the other riding section of the forum, I have always though of making subforums or sections of their own for GD, Amargosa, Logandale, etc. Many Dumont peeps frequent those areas as well. That may be a good idea.
