Regarding "the world is your urinal"....go to a camping site & ask about it and you will here how camper don't agree with guys doing that. Think of the poor wildflowers, critters & everything living there, those guys are harming them. One thing that was 'nice' (but sick) for him was when we would go camping & at night he could just step outside and walk back to the bushes but I had walk 'more than 200 yards' to the shower/potty house or sit on the plastic porta-potty about down on the ground. I talked my DH out of using the bushes any longer (sometimes he uses the porta-potty)
When my SIL & her DDs & their dog were traveling here to visit they accually used a jar for their male dog. No stops needed.
