Colorado Beer Assistance

So I was hoping for some advice from you guys. I have a friend going to Fort Collins Colorado soon and he has agreed to bring back some beer. We live in Cypress (Houston area) Tx. We get some decent beers but there is a lot we cannot get. So what beers should I have him grab while in Co? I love ambers, browns, stouts, and wheats mostly but I don't mind an Ipa from time to time. Thanks in advance.
