I tried out some dispersed camping here at Hanning Flat and I was driving towards the lake and my car got stuck in sand. It was a dumb mistake but I learned my lesson. Luckily, I was able to make phone calls and use internet on my phone from here. I called for help and got out. Just a warning for any off-road newbies out there. Pay attention and don't drive towards the lake unless you know for sure your vehicle can handle sand and make sure you have a shovel and a tire traction device with you in case you still get stuck. Here'a photo of my car in the sand and a pin drop to show the location where I was stuck.
