Practically all national forests across America. All public land following certain rules. And you don't plink while doing S.t.a.l.k.e.r retard. The goal is to be a ghost. You also have to do them on private land where firearms are illegal to carry unless permission from the owner is given. I'm one of the anon on /k/ that came up with some of the modified challenges in 2012. If you plan on doing them, know that you will be at risk of multiple felonies and prison time from possessing a firearm while trespassing. Serious offence.
Having said that, I've been doing them for years. Know the area. Scout days before and watch to see if there are patrols or if the land owners go there often.
