Jerry Cyr, the Park Operations Manager for Delhi, Dexter-Huron, Hudson Mills & Huron Meadows Metroparks, was nice enough to get back to me regarding the course and the tee pads in the winter time (see my post regarding the email I sent him a couple pages back).
He said that for the league members that play out there (A3, etc.) are welcome to use their in house shovels & salt anytime, just remember to return them.
Better than nothing I say - looks like asking nicely paid off.
So if you're an A3 member and you go out to play in a group (includes myself) and the pads are a wreck, please do some work! We usually make it fun, and have the person who shot the worst in previous hole drag the "shovel and salt of shame" (i.e. they clear the pad and carry the shovel, and yes trash talking does ensue).
