getting a charge

Hi, I wondering if any one could help me out. I was thinking about coming out to the eagle river area at the end of August from out of state. Because money is tight (I guess it's for a lot of people), Me and my boys would "rough it" at a campground on a lake. The only problem I would see is getting my trolling battery charged. I can bring an extra, so would only need the service two or three times for the week Is there any where I can do that? I have the charger, all I need is some juice. Thanks, Steve.

i am also goin up north the end of august and we usually camp at the chain of lakes campground.each site has running water and electricity.the campground is located on cranberry lake.hope this helps!

How much is it a night over there? The campground I would like to stay at doesn't have electric, but fairly cheap. Steve

its 25 dollars a night i believe.very nice place,ramp,docks,pool,store.they also have a trailer for rent if ya dont wanna tent it.
