What is the firewood policy? Can we bring our own? Can we use any we find on premise? Is there firewood to purchase there?

Save some money and bring your own firewood. Buy from the store as last resort.

They frown on collecting firewood within the campground, but sell it in the store. All sites have a fire ring and/or BBQ.

You can bring your own. Or you can buy some from their general store. They have showers and Laundry facilities.
