Re: Boat Visit!
People will treat you the way you allow yourself to be treated.
If you act as if (1) your time is valuable, (2) you know what you are doing, and (3) you realize this is a buyer's market, you can avoid trips like this one.
Frankly, it appears the seller abused you. Demand more information from the seller before you spend your valuable time on the road.
I had a seller or two who offered to allow me to visit their boat after giving me the combination or location of a key to the lock. I declined. That type of seller is not motivated.
