Hi there – welcome to partyvibe!
There’s a sub-forum marked ADS-US which mostly shows commercial events in the USA. They do appear to be skewed towards a certain collection of states; presumably other states have harsher laws and do not allow raves to happen!
I have to admit though this board has become a bit UK/Euro-centric recently; not sure why TBH as its always welcomed posters from all across the world.
There are still quite a few people on here from the US (and much of our drugs/political news posts come from US sites) so hopefully you should find something you like and/or make new friends. Its always good to see more posters from across the pond….
