Curious that most posts here seem to follow the line "It doesn't matter how long you take but I took ***.* hours to mine!!!".
I'm not telling you how long I took, but I did have four of them. One in 1956 in a glider (ATC), Two, in a glider 1980, Three, Cessna 150 1986, Four, Cessna 152 2006, NPPL 2007 July. Enjoyed every minute, & will say that each successive solo took longer to reach. Age does that!
