Hi, I'm thinking of camping at any of the Mogollon Rim area campgrounds near Woods Canyon lake in May.

It looks there are many to choose from: Aspen, Mogollon, Spillway, Crook, Rim Campground, and Sinkhole campground. However all of these appear to be first come first serve on recreation.gov

Anyone know if these are competitive/hard to get on a weekend in May? I'd be going up either Friday morning or evening.
