Isn't there a famous story of the guy who went to the States to hour-build, rented a Cherokee, flew it to a deserted strip, tied the tail tie-down to a tree and sat reading the paper with the engine at cruise RPM all afternoon to build hours; recorded on the HOBBS meter of course but got nowhere near the sky? The story is he couldn't be ars*d flying as he felt there was no experience-benefit plodding round the CAVOK skies all day!
