Where is that slip in the photo? Looks like one of our local lakes in Arizona.
Lake Pleasant which is 1/2hr drive from my house and 12 miles long has a 10 lane ramp and a 4 lane ramp. Fees are $10 per day or about $110 per year.
Includes a shuttle van to take you to and from ramp to parking area. However it can get crowded at weekends.
