I talked to two local paintball places this month.
Regarding liability, both places require substantial liability waivers. One requires notarized liability waivers. They are not responsible for any injury. They list possible injuries including everything from loss of vision to death.
One paintball place said they get a lot of scout groups even though they have heard it's not allowed. The scout groups camp out nearby and "disband" the scout function to go play paintball.
- Judging from the waivers, liability is a big deal
- Despite the ban scouts playing paintball is happening regularly
- The "It's not a scout event" wink-wink, nudge-nudge tactic is common
Just sharing my recent experience ...
