One other thing not mentioned is the fishing.  I do a trip the first week of June and one mid-September every summer.  First week of June is usually great walleye fishing.  September is hit or miss for the walleye.  They may still be 20 feet or they may be 5 feet in the evening.  September, bass and northern are usually very aggressive unless you get one of those early season snows and that usually shuts things down for a day or two.  Just my past experiences.  But agree with rest, especially about the weather.
