I've done longer trips professionally but my round-Britain solo was the best use I've made of my PPL and a heck of a lot of fun.
My previous thread about it is

G-LEVI.com.
PS If you like what you see, feel free to click a few of the ad links on the group website to help keep the show on the road. Cheers, WeeMan
