I did this when I got my license. I had 60 hours, and would just take off and head west while looking at the sectional and then choose an airport.
I kept track of fuel in time like above.
About the time I had 110 hours, and had been building time regularly, the flying club started bugging me asking me where I was going, so I'd tell them Iowa City, Dubuque, Quad Cities, etc. Somewhere west. Sometimes I wouldn't go that far, sometimes I'd go farther.
Then they started bugging me to plan routes, and then show them, so they could approve them before I could even pre flight the plane.
Sure I showed them when I did plan flights, which was like a little over half the time. I'd just go home and let them eat the loss of a 4 hour block on a weekend when I didn't plan the flight.
I haven't rented there since they asked me to start giving them full routes and to explain why I did things. I never did anything wrong, all my buddies thought it was nuts (none of them rented from this airport.)
They'd even have an attitude when they heard I had rented somewhere else, or flown a big cross country with a buddy in another places plane. Like they owned me!
I spent nearly $7000 Part 61 on my private license at that flying club over a year( I had become wise to the fact their CFI was milking me for hours after doing stalls and ground refernce manuevers. I passed the checkride no problem, and in very little time. I called American Flyers and Illinois Aviators and then kinda commented that I was thinking of finishing up there, and all of a sudden, I had my ticket in a month...jerks) I had taken my disco there 4 years ago, and they knew who I was.
They drove me nuts, they sucked. Every time I wanted to fly, I would get to the plane in the hangar, the engine wasn't plugged in so it was impossible to start in the cold winter, it would need fuel, and oil. Every time!! Then I had to find someone to give me the "key" since some pyscho tried to take on of their 152s on a joyride.
The lineman, some old guy, would complain about having to put 10 gallons of gas in the tanks, "you don't need to have full tanks every time.." Shut up, and do your job, you sit around all day, and the most work he did was attempt to marshall the lone bizjet that came in every other week by raising his arms above his head, if he did that. HA! Nice coushy city job!
We won't even get into the leaseback planes, which they had one 172, which was on leaseback. 2 times when, after I had PRE FLIGHTED, the owner, just shows up, and takes his plane. Hey it's his plane, but the flying club needs to enforce their scheduling rules if its part of the contract!
end rant!
Flying around with no purpose is fun.
