I am going to give the end of South River Road a shot this weekend, but it has been a long time since I have been there. What is the latest you can get in there? I have heard you can stay as long as you want due to the automatic gate (props to the dnr) but what time does the entrance lock? Also curious how crowded it will be last time I was there it was shoulder to shoulder. If anyone has a better idea or some insight pms always welcome.
