Dispersal Spot suggestions ID/MT

My install date is 4/30 in the late afternoon. I’m coming from the Hood River area and looking to dispersal camp Friday the night before, somewhere close to Bozeman the night of and then some place on the way back (this is unfortunately a quick trip with minimal exploring. Would like to camp ~1/2 way on the way there and back. If anyone has any good suggestions let me know. I was thinking the spot along the Lochsa across from Wilderness Campground but I’m not sure if the Lochsa will be drawing large enough crowds to make the dispersal spot rowdy yet or not.

Any suggestions are much appreciated!
