If you're headed to Yellowstone (or camping or somewhere the traffic is potentially LONG/stopped) I recommend getting THIS.this portable POP UP potty holds adults. We also have a smaller one in pink that always stays in the car for kids. But this time we opted to fold up this in the backpack JUST in case there was a long bison stop, or not a bathroom anywhere near.I think the adults used it even more than the kids 😆It saved many pants.p.s. the "bathrooms" at Yellowstone are a random hole in the ground in a concrete block. Trust me. You need this. yellowstone musthave travel livinglargeinlilly momlife travelhack parenthack LTKActive LTKFamily LTKTravel
