I've been pondering about this for a little while. Some of these places would be cool and possible if the local security would allow; some are a little more fantasy-based, but would be fun were it possible, nevertheless.
- in the Colliseum in Rome, Italy, gladiator-style: need to have some large bales of hay or something on the arena floor to offer cover, but otherwise it's nothing but sun, sand, and heat between you are your opponents
- on the Eiffel Tower in Paris, France: lots of stairs, various levels and platforms, but while the iron girders offer some protection, a slight adjustment of positioning can open up means to soak another hiding around the corner
- in the International Space station: yeah, water's not great for all the instrumentation in there, but a water fight at microgravity would be quite fun; straight-line water streams.
- in an abandoned steel factory (or something similar): some sort of large building/warehouse with various levels, stairs, plenty of hiding places as well as some open expanses for varying styles of water combat; no working machinery or electricity as well as no broken glass/rusty nails/etc left around, though, to reduce the chance of accidents
Some other locations, some mentioned before, are also places that'd I'd love to battle in:
- Eaton Centre (inside the mall), Toronto, ON
- Central Park, New York City, NY
- Boston Commons, Boston, MA
- Yellowstone National Park, WY
- Haleakala crater, Maui, HI
