HI there. In the past, we have gone to the desert or mountains, mostly boon docking. We have been to a few campgrounds, but things were pretty clear. Today, we tried to use the reserveCA thing, and it has changed a lot since we last used it. There is no clear specification on sites that allow pop ups and since ours is fully hook-up-able, I am not sure how to book. Of course, we couldn't get a normal trailer - had to get a unicorn. haha. Any thoughts?
