24M4A looking for pee holding challenges to do in public in a city

Hi, I’m looking for some pee holding challenges ideas, maybe some scavenger hunt. I'm into omorashi, pee desperation. Currently I live in a big city, I have free public transportation (metro, bus, train). It’s very hot in here. I usually leak before actually peeing myself, so there’s a chance that, if I stay outside I can slowly leak everything out and have it dry off as I go. There are plenty of shopping malls, cafes, fast foods etc. I don’t know the city very well though. I might partly hold at home. (Mind, I don't live alone)
I can provide more details in PM. I'm not interested in being controlled by someone in real time, I'm only looking for challenges, tasks, things to do. (drink this much, go to this place, do this and that, now go there, do this, now you can go home and pee). I'll provide detaile report of how things went and maybe some pics too.

Other non-pee related kinks are also welcome

PS. I have also one more thread on pee holding on my profile.
