Pro:
Not that big. Max 10.000 people. Nice overview, 2 stages, but one is in a tent, for smaller bands, most black/death metal, no crashes, as the 2 stages are not (always) simultaniously., reasonable price. (but €3 for a .3l. is a bit too much, but then again, it's apparently a normal price)
It is an airport, we were close to the airport strip. Meaning if heavy rain, your feet are relatively dry, du to the concrete.
Con:
The trip with public transportation is a bit hazardous. The nearest railway station is Mühlhausen (Thür), and it's all in 2 hours interval. The shuttle runs every 2 hours. (so do the trains actually, but from more than 2 directions, most Erfurt (Hbf))
Nearest village is Schlottheim, but you need a vehicle to get there, or a shuttle bus.
And if you can't have a reserved spot, you're pretty far from the stage. It is after all an AIRPORT!
And... apart from the tent, there is NO SHADUW! With the heat from the last weeks, a BIG problem for me.
And sometimes the sound is better at the camping, than on the festival area.
But I plan to go there again, be it in 2 years. (no, no 2 festivals after one other!
