Definitely a "car-camping" area.  You're so close to the interstate it seems as though a semi is going to run right through your tent.  The river is within short walking distance and if you're walking with anyone who has no internal compass, you will end up lost in the woods for about 1/2 hour trying to get to the riverbank without having to jump in and swim.  A cozy, casual spot to have cookouts and drunk shenanigans with friends.  Hiking and bouldering are close by on I 90, but I won't recommend this site for anything but a leisurely trip.
