Yes, without question.
If I was young again I would do it (maybe I would change few things). Its not when you leave that matters, because you will always look back with found memories and say "....it's not the same as it used to be....." it is when you join that is reaslly important.
It is very different now to when I joined, but that does not mean that they were necessarily the "Good old days".
Try it, and if you do not like it get out. You will only regret never trying!
