I went to the field during my training days, instructor was at a pattern contest. I was alone, my NexSTAR Select, and grass that needed cutting. Well, I said to my self that I would practice taxi-ing around until someone showed up that could buddy-box with me. I did the taxi bit for a tank full, refueled, and went back to the taxi stuff. Well, as you all know, deep down inside, something said that I can do this so I added a little throttle, then a little more, then a little more, then.... airborne!!. (the grass needing cutting bit was neat cuz you could see my taxi trails all over the place..ha)
Ok a__hole.. what are you going to do now!! Ok, so I orbited a few times then setup for a landing.. greaser!! Perfect, centerline, flare and on the ground like it was nothing. I taxi'ed around and setup another take off and went airborne with this enormous

.
I didn't realize it, but the club President had driven up and was watching. When I finished messing around with my take-off's and landings, he walked up and grabbed my shirt, was going to tear it off (custom for when someone solo's) but it was a tad bit cool out so he didn't, but yelled to me... 'HEY, I SAW THAT!! YOU CAN'T DENY IT.. YOU SOLO'ED!! CONGRATS!!' .
That was about four years ago. Now.. well, I fly just about anything that I can mount an engine, and a radio on.
Best of luck, and CONGRATULATIONS!!!
