While some here "joke" about "pee bombing" a trailer park.....FWIW....... Last I read in USA regs was, "don't drop stuff to hurt peeps or property......".....
while I agree that adding to garbage on the ground is a no-no.....dropping in a field or forest is "sorta OK".
Didn't hurt anyone/anything......
Yes, garbage is garbage, try to avoid......

I still use quart sized ziplock baggies....but I leave an inch or so loose to allow weight/liquid to drain during decent so a few pounds of mass won't hit the ground.
I have not flown enough the last few years to get an external catheter to hook up to ship dump system.....
I do NOT agree with pee bombing anything....although it is sorta funny.....to me......but, I am a dad.....we likely have an odd sense of humor.......just ask our family.......LOL.......
