First off, Welcome to Xmarks!
Are all 40 of your group going to be Camping?? If it were me and that was the case I would be
there by Sunday July the 5th at Grandfather. Camping will open on Friday the July 3rd.
Setting up an area big enough for 8 to 10 tents will need to be early on.

The tent camping area does not fill up at the first of the week usually but by
Wed. it will pick up greatly.

We call the tent area Tarp City.
You need one for the bottom and one to go above your tent. Grandfather can
be quite wet at times.
