I suggest everyone watches the video that Megan posted.
Lots of good information from a well respected pilot.
The most obvious comment made in that video was "could have just towed the aircraft the 3 miles to the airport" which really sums up the accident.
Why attempt a difficult or dangerous takeoff from a road when you could have just towed it?
As Scott says "If it's difficult, dangerous or different" then don't do it.
