Well, are we looking more towards summer, or more towards fall? Around here, august tends to be the most reliable month, weather wise, but it's usually also the hottest month. September can go either way - last year it was still in the high 80's and muggy in September, but the year before that it rained about the whole month. October it "traditionally" the time everyone visits Brown County - people always want to be there when the leaves are changing, it IS beautiful, but again the weather is unpredictable and if we wanted to get in in Oct we would have to book our sites like, NOW. I think if we want to be able to count on the least chance of rain, July/August is going to be our best bet - just be prepared for it to be hot! However, Brown County does have a couple creeks we can cool off in, and there are wash racks in the horseman's camp to hose the horses down as well. Just stock up on tank tops, sunblock and bug spray!
