If the access is a privately owned road the county would have to either negotiate an agreement for public use, buy the road if the owner is willing to sell, or exercise eminent domain and take it through court order with court ordered compensation.
Not to hijack this thread but is this better? If you look you can see that his arms are not fully extended but his elbows are actually close to his ribs. Last year on July 5, my brother-in-law caught this on Lake Osakis while we were working jigs and minnows for walleyes with my nephew. We are not bass fishermen but catch a few nice smallies occasionally when chasing walleyes. We didn't measure or weigh it but we both agreed it was probably close to 25" and he thought it weighed close to 9 lbs. Afterward, when his son kept needling us for releasing it, we looked up what a 25" smallmouth might weigh. What we found was 8 lbs - 4 oz. give or take. Then looked up the state record and learned it was entirely possible that he may have released a new state record. As far as he is concerned it was.
