Boring Practical Stuff
If you plan to stand near the stage, you WILL experience moshing, and may in fact be forced to help a fan body surf just so he/she does not fall on you (watch Godsmack clip). If this all sounds exhilarating, you will enjoy a rock concert in almost any venue.
If not, search for venues that offer balcony seating so you can safely enjoy watching the moshing, body surfiing fans while also seeing the band. You won't be able to see the band members' faces clearly from a distance, though.
FYI - All hard rock concerts are General Admission, and NOBODY SITS!
Where do you suspect I choose to stand to watch the show?
