Replying to CU Boulder Skiing options?

Hey so i'm going to Boulder for school next year and a friend of mine suggested i ski at Eldora mid-week and make the trek over to like keystone for the weekends. Fist off is that a good idea? i hear Eldora blows for all types of skiing, but i also looked at alot of threads saying they are picking up their game as far as the park scene (what im interested in mid week). Also is there a bus that i can take that will get me to keystone? I'm just interested in what my options are. i'm sure a lot of kid going to boulder are faced with this. let me know
