Sugarbush max's out on water regularly so I don't think those rental compressors would do much. From what I understand there main constraint is water now.
Yup...they got rid of rental compressors because they simply don't need them with the newer more efficient snowguns. In reality, even their permanent compressors weren't all needed this year. At times they were able to run the system to full water capacity while only using 1 or 2 of their 3 compressors at LP for example (going off memory of the numbers, but I think those were what was said).
