president bush at camp lejeune, NC

today i had the opportunity to see president bush on camp lejuene..i noticed something very odd while witnessing his convoy...i was one side of the base and a friend called me saying he just saw the presidential limo pass him...then while i was on the phone with him which was a 5 min call i saw the presidential limo with the convoy..i know this had to be 2 different convoys because the base takes 35 mins to get from one side to the other...could anyone help me out? have u ever heard of a "mock" convoy???? if so please help me out

Remember that the President doesnt obey the speed limit when he visisted Ft. Bragg he was there very quickly from the airport. No Traffic and they go bout 80 or 90
