I live on the west coast of Canada and the rave scene out here is pretty big. There are tons of local DJ's that run small promotional companies, and constantly host illegal outdoor raves in secluded areas that are
extremely well organized. I still get invited to these events on Facebook constantly, although I have not been to one for well over a year.
I used to go all the time though. You buy a ticket at a licensed vendor, which has some information on it (including a phone number). On the DAY OF the rave, you phone this phone line about 2-3 hours before the rave, depending on where the location is, and they will give you directions to the spot from all directions (whether you are traveling north, south, east, west etc. along certain highways). When you arrive, they have traffic directors who help you park your cars to leave room for emergency exits, and to avoid people getting "stuck" anywhere. They also have fully licensed security on hand at all times, and first aid for people who need it.
Once you unpack, you walk into the rave area and they always have these massive stages & light shows set up in the middle of buttfuck nowhere, like a clearing in some logging road in the forest haha, or in an abandoned shack up on the top of a mountain property

And its fucking awesome, hundreds sometimes even thousands of kids show up and set up tents or roll up in their cars & trucks, and everybody starts popping and drinking and dancing. They usually pack up the next morning and go, but I have been to more than a few where they go for 2-3 days straight or from Friday night until Monday morning. The music is always incredible and they showcase the best local talent, aswell as often flying in well known DJ's who are touring in the area.
These raves are incredibly fun and rarely busted up by the cops (although it has happened before). I have tons of good memories of being in highschool or just after, and planning these weekend rave trips with large groups of friends and road tripping out there with suitcases full of drugs & alcohol. Fun times!

I have definitely noticed that electronic music is becoming increasingly popular and "mainstream" now, so raves are getting more and more organized and actually starting to land really dope venues, like massive arenas and local stadiums which will feature some of the biggest artists in the world.
