I may try and find somebody to meet me there that knows the place pretty good.
Post up when you plan on going. If I'm there that weekend,, I'll try to hook up with you if you can't find anyone else to tag with. Our first trip this year will be Nov. 11,12,13,14. It'll be a family trip with all the kiddos,,, so if you can make it that weekend, it'd be a good "first" weekend in the sand for you. (slower pace with the kiddos and all)
The dunes are like nothing else you've ridden before. (assuming you've never ridden in them) That's not to say they are hard,,, just very different. It'll take a day or two to get used to them. (a bit longer if you ride on 2 wheels)
What type bike/quad will you be riding? I wouldn't make the trip without paddles. (depending on the bike that is)
