Somebody had earlier requested a photo of the berm that flanks one side of the fields at the new practice facility. I'm not sure if this photo does it justice, my guess is it is 25 or 30 feet high with a pretty steep incline. Players have been running up it to get in shape. And next year, you too can run up it so you can watch practice from the top.
I think it was placed there to shield the fields from prying eyes along the road that runs in front of the facility, as well as to offer a place from which to view practice. The opposite side is the lake, and there are trees and bushes newly planted that will shield the field from boats at some point.
