Yep, makes sense.
I wasn't sure if it was everything you listed, or just the refrigerant system. I thought their ice was good the last time I was there, so I'm surprised they would replace all that equipment. Nice to know they've made that much of an investment in the plant and facility. That means they're not turning it into a Home Depot anytime soon!
The original owners (personal/financial problems) tried to keep the rink open until the bank could find new owners, but the bank decided to shut down abruptly several weeks early. We've had temps in the 90's and 100's for two months. That must have been a boon for the renovation because the ice was completely gone when the new owners started work. They took it down to the ground - all new boards and boxes, too. I'll bet they laid a nice, solid sheet last week. Now, I really want to go to the grand opening, even though I don't usually skate or coach there.
I hope this place does well: they have the land to be able to add a second building/sheet of ice. (My current one-sheet rink is land-locked.
) If they made that much of an investment, perhaps they build in expansion capabilities.
I can dream, right?
