Will I be able to have fun there with my non lifted Jeep? Are there areas for mild-moderate wheeling?

Yes if the gambler 500 crew could have fun there, anyone can YouTube it if u don't know what it is

Yes! I have a pretty much stock Wrangler (the only mods are a new front bumper and winch). It's amazing the trails she was able to get through! It's definitely a blast. I would suggest having a CB or a buddy with you just incase. Especially if they don't have a winch
