Ah, Metalcamp. I was at the first four or five until it started getting old (or I did). An entire week of camping, swimming, drinking, eating, and bands. I started to whittle away my time there from an entire week to a few days to just going to see one or two bands for one day (I live right next to Slovenia) until I just stopped going altogether.
Too much of a good thing really sucks. When you've seen so many bands and the lineups don't really get you excited anymore, it's sad. Nostalgia's a bitch.
