Just a reminder, for you young whipper snappers:
The solo cross country for PPL used to be hundreds of miles not 150 miles.
My first cross country solo, in 1964, was from Peekskill Seaplane Base, Verplank, NY 7N2, to Cleveland, OH (BKL if I remember correctly, or maybe it was Lakefront) and back in a PA-11 Cub on floats. My logbook is packed away in my childhood home in Peekskill, but I remember I left before dawn, it took me all day to get there (head wind, and flying to find fuel). I had to sleep in the plane, then came back the next day. I had used so much fuel getting out there, I didn't have enough money to get back home. I landed in Jamestown, NY with $3 and some change in my pocket, so they took up a collection for me and bought me fuel and lunch then sent me on my way. Yes I did fly farther than I had to, and my old man tanned my hide for doing it, but he didn't rat me out to my mother, who hated airplanes, and didn't know I was taking lessons.
Five hundred miles?
Go for it.
