Why The Sea Store Matters
You don't have to drive to Madison.
The closest grocery store is 9 miles. The closest bait shop is further. The closest gas station closes at 9pm. The closest ATM is at the bank in town.
The Sea Store sits directly across the street from the resort — same family, same standards, walk-across distance. A weekend at Hillside doesn't require a single trip off the neighborhood. Whatever you forgot, whatever you ran out of, whatever you didn't realize you'd need until 9:45pm on a Saturday — we have it.
Officially: Cones, Casino, & Conveniences. The soft-serve cones are a real thing. Bring quarters for the gaming machines.
