You shouldn't be scared of it but you should respect it. I think one of the best settings for trying it is at a music festival. You have a shit ton of music playing the whole time, great energy level, other people having similar experience, don't have to worry about family cops shit like that, no need to drive anywhere, ambulances and shit are there worst case.
Make sure you get something good and take it easy. No need to go crazy first try. (although that can be awesome, I'm sure it could go the other way as well)
Will try this vid another time. It hurt my eyes trying to focus. I don't think I did it right anyway
