Bottomless Lake SP near Roswell is a good stop for a night or two. It had a bit more character (think New Mexico desert) than Lake Brantley SP in my opinion. Part of reason we stayed there was to avoid pulling the 5th wheel needlessly to Carlsbad since the trip was head north after leaving Roswell. One of the offbeat things not mentioned about Roswell is the aircraft boneyard (storage) of old airliners at the airport south of town. Second offbeat thing is the alien themed McDonald's in Roswell. Less offbeat is the art museum in Roswell. I don't recall the name or details but it was a worthwhile stop. Don't forget to have at least one green chili cheeseburger while in New Mexico. The good ones are truly special.
