I was flying a rented Cessna over water, with a sleepy passenger...do other pilots get nervous flying over wide expanses of water? At about 12,000 feet, I was flying under control, abeam Tallahassee, Florida. The controller noticed that I was wandering a bit, and so I was, having noticed that the fuel gauges did not agree, one said nearly empty, the other read full. He gently reminded me that I had strayed from the proper heading, and I said, well I wasn't certain whether or not I had a problem with the fuel gauges.
Instantly he came back and asked "Do you want to declare an emergency?" Not really, not yet. The controller said that Tallahassee was abeam, about 30 miles or so. That seemed like a good idea. The controller then told me to turn on the heading for Tallahassee, and descend to 4,000 feet. I said negative, If I am going to be flying a glider I want as much height as possible! The controller agreed completely, said he had cleared any conflicting traffic, and I could come in to the State Capital at any altitude I required. So I did, and having the airfield in sight, I descended, landed, taxied to the apron, and ascertained there was plenty of fuel in each tank, and so no worries, as typical of a beat up rented Cessna. Getting dark by now - it gets dark quicker if you are flying in December on an Easterly course. Anyhow, no further problems, arrived safely on a beautiful morning, St. Petersburg Florida. My passenger had every confidence, slept the whole way!
