Re: Being there on your own.
go! I've gone to tons of concerts by myself. I've even flown to different cities to check out bands and not known one person. I always end up meeting people, and it's really cool. I have to admit though sometimes I do bring a camera along just to keep me busy if things are awkward.
45 minutes doesn't seem too far to drive to see a band, unless they play in your area often.
