I've been to several away games and bowl games with HANC and kc_husker. Including KU, CU, and several bowl games. KU is a great atmosphere for away games since it's mostly Husker Red in their stadium. Pretty decent tailgating there. CU is fun if you can put up with the idiots out there. But there is a large hotel close to the stadium where all the Husker fans hang out, at least that used to be the case when I was last out there in Boulder in 95. ISU is pretty awesome tailgating too.
I would love to go to Texas and Wake this year. I wish I would have gone to A&M last year. I'm looking forward to some of our future games with Tennesse, V-Tech, UCLA and Washington. A night game at Tennessee would be pretty crazy.
And any bowl game is great to go to (well with the exception of maybe the Independence Bowl). We've had a lot of great times in San Antonio, Dallas, Phoenix, Miami, and Pasadena.
