I haven't checked 'local' time for here:-
http://wikimapia.org/#lat=40.0003666...16&l=0&m=a&v=2
but he should be able to leave after 10.15 GMT
(Just checked and it is still EST - GMT-5, so he's clear to leave @ 05.15 local)
Further edited to add he's achieved
one tenth of his journey (270 miles out of 2700 miles). He's driven for 5 hours so far (average speed 54 mph - sounds a lot! Have I counted right? Includes a 20 minute stop . . . )
