yea momentum normally has them, i did it for a day last year, you have to pay for your lift ticket though which kind of sucks ($55 per day) since your normal summer pass wont get you up in the morning. I personally didnt really find their park all that great, so i didnt think it was worth it. Digging at COC would be sick but you need to know people to get in there. If you still wanna do it though just send them an email and a resume. Maybe dave murray has spots too, but im not sure seeing as theyre pretty small. You could contact them as well.
