*cough* Anime St. George rocks socks. It's only about 2 hours from Vegas and is on the 25th of Sep this year. >w< *cough*
I went to Anime Vegas last year and in 06. It was good in 06 and wasn't too bad last year even though we spend most of our time in the dealers room. We did have some problems with the staff though and their change of venue is keeping us from going this year. It's not a bad convention, but just not one my group and I will be attending this year.
