I've done the two car shuttle. (A variation of this is I park my truck at Trail's end and a friend drops me off at the beginning - and the friend goes home or wherever.)
I've biked (I like to bike at the END of a trip when my food bag is nearly empty).
I've thrown myself on public transport (On my Colorado Trail through-hike, I hitched the 3 miles to Durango then arrived at a bus station. At the end of my AT thru-hike, I took a mix of hitch, bus, train, bus, and family pick-up)
This summer I'm going even more elaborate by FLYING in my other car (with my girlfriend who will rent a car for a week). I will park my truck near Whitney Portal, then in her rental car we will tour SEKI and Yosemite. From there, I will start my JMT hike and she will return to the airport. This would NOT be my first choice except that she has to work and I will hike the Tahoe Rim Trail before she flies in.
And the final option is the "Chaufeur", a GOOD friend or significant other who drops you off and picks you up at predesignated times. This also applies to my NOLS days when a tan school bus dropped us off and picked us up.
