I know their address...and the dirt road leading to their house...there is no gate you can see from de arboles to carvers home.
there are two structures, big homes not too far from each other on the western side of de arboles...but two different properties/ entrances, maybe...50-75 yards from each other...the entrance to the "smaller" home (not their home) is paved....with a metal gate.....right across that entrance on the eastern side of de arboles is another entrance to a different property....i see the intercom stand and the two very big pillars which serve as part of that properties metal gate.
so if carver was driving fast....cause the dirt rd to his home off of de arboles... was still another 75 yards from that very slight curve, its possible he ..could..have veered off onto the eastern edge...hit the intercom pole/stand, then into one of the pillars, not both....and that would have been at the front gate of A residence....about 75 yards from the dirt rd leading to his house.
So from what you have written is a match with mine....and assuming he didnt handle the **very slight curve...
if thats why it exploded into flames....i wouldnt know....but what about brake marks??
the only way this could have happened is if he was driving real fast....at least 70-75...veered off onto the edge.....*****and didnt brake****....THATS what i dont understand.
