I am not taking anyones side on this. Yes it is a terrible thing that the deal did not go through. 4.5 hours and 165.00 in gas.
But the thing about trading stuff for stuff, everyone has to feel comfortable with the trade. I have seen trades both work and not work.
1 person gets cold feet, right or wrong, the guy did not feel comfortable with the trade.
No goods changed hands, no money changed hands, other than the day and gas burnt up, it could have been much worse. I'd consider myself lucky
