Brower park is a good place to camp. Also Sandy Beach is not bad from what I understand. Brower is a Mecosta county and I believe Sandy beach is a Newaygo County park. They both can be found on the WEB.
As far as the noise laws, I have not seen anyone pulled over due to this at Hardy but, there is always that possibility. Also there is a new store up river from Brower that is pretty well supplied. Now just outside of Brower is a new meat market(beef,chicken, etc.).
I may be up on that weekend, it will depend on the weather. Dwight
