How fast does Two Jack campground fill up?

[Battery]

Hey guys,

Looking at heading up to Two Jack (main) this weekend for Saturday and Sunday night and won't get out there until 7 pm or so, will we still be able to get a spot? I know the last time we went, we went on a long weekend and got a spot early Friday morning, however I'm not sure how busy it gets on a normal weekend.


Thanks!
