WOW !!!!! this is a tough crowd to please.
Looks to me from the pictures that the one guy had no problem backing into an empty ramp and getting their boat on the trailer.
The other 2 ramps were probably open by the time you were ready.
Gee 10 minutes is really not a big deal in grand scheme of things.
The average person who doesn't frequent a boat ramp often probably gets a pass by most people. A live release trailer from a trail should numer one have the common courtesy to know boat ramp etiquette and number two use some common sense before blocking the middle 2 lanes of a ramp.
Sorry I know that isn't a "feel good" and "try make everyone happy response", but it is my honest opinion on the matter.
PS what the heck happened to BLT? Is the trail dying a slow death?
