Good thing we decided to stop at Outdoor Adventures on the way home from the State Park because the traffic on I-75 was literally stopped. We tried to get gas just before the exit onto the expressway only to find the station had none. When we got to the ramp we noticed that the traffic was horrible. We found a way around it and made our way to the park.
Even though the expressway was like a parking lot, it is good to see people camping again. The last few years here in Michigan have been quite slow.
