Yesterday was possibly the busiest that I have ever seen the area that I was, which is usually pretty empty. I would bet the main lake, bike trail and other more used areas were packed. Hopefully that doesn't shut down things down for us that stay away from others.
This time of year for me, is hit or miss. The water is still pretty cold. I was wading with my boot foot neoprenes with thinsulate in the boots. My feet were numb by the end of the day. If someone ends up falling in, I can see that forcing the issue of closing.
