The only "rave" type situation I would even consider doing a decent dose of a psychedelic drug (1.5-2 hits LSD, equivalent doses for other things like 2cb, mushrooms, 4-aco-DMT, etc) is at an outdoor psytrance party. Or to use the colloquial, which I do quite often, a "bush doof".
If it's your first time, do it in a comfortable place surrounded by people you trust. If you feel confident after this, try it in a trance club or maybe a rave if that's what you're keen on. It can be enjoyable, even though I haven't tripped at a hard trance rave, I think I would prefer tripping in a more relaxed, intimate place like a club. Which I have done numerous times, but on light doses. Never more than a hit. When I went over that limit I freaked out.
My preference however, as stated above, is a bush doof. Seriously, get yourself and your mates to one of these once you've got a few trips under your belts, it's an experience which you will never forget, and hopefully one that will get you into the scene. Although doofs can be and quite often are as hedonistic as raves, they seem more special. You're less likely to find fights and such at a doof as well. I have heard Northern NSW and QLD sometimes get the dodgy element around, but excluding the commercial partis held in Victora (names excluded, am I allowed to list them mods or no because it's in relation to drugs?), I have never experineced personal threats or anything like that.
