Hamburg is a real cool show. Has almost an underground feel to it. Lots of stuff crammed into a small fieldhouse(at least it wont be hot when you go, no AC).
They have stuff you might not see anywhere. Want a Gaboon viper ? They'll have it. I watched a kid that was like 12 walk out with 3 rattlesnakes, a hook and a smile.
Adult bps are a little harder to come by but i'm sure they'll have something you want. Yeah, you'll be a kid in a candy store. lol
