I flew in there once in the C-21.  They obviously don't have contract gas, so plan on tankering some fuel.  As long as the weather is nice, its not a real problem.  The only thing we had to deal with in the -21 is with our pressurization system.  Since our emergency pressurization kicks in around 9500' cabin alt, we have to turn off the auto pressurization and revert to manual.  Not a big deal, just a little non standard.   
Before I left, I remember us being restricted from flying in there but can't quite remember why.  It was a squadron-imposed restriction though.  If you have time, swing by Eagle, CO.  They have contract gas, super nice FBO, and they will give you free T-shirts and hats.  Highly recommend!
