well, i have been to a lot of fantasy larp (orcs, elves, mages, fighters and metal armour+larp-swords) and it was always ok or good.
of course you donīt like some nerds/to-much-in-persons, but I have the impression that here it is not as "personal".
regarding the police: it was never a problem. the german police might also have less of an ego trip--
I never had a situation where they drove by and flashing the lights (ridiculus...) they tell you to calm down or they beak up the party, but this kind of "watch out, we sit here"
regarding the lawsuit... that is so funny... I guess all the usa cliches are so true
well, in summary, I like larp, but I think vampire is a lot more problematical, because they all like ego trips..
and that is when everyone finds out I am Caitiff.
well, that is a good example..
I will stick to fantasy larp and have fun fighting with plate armour and sword!
