dear California-Atlantic-Florida Fronts piece wanters and havers

how interesting that photo series is

mi roof rack is a little different as well---
rather than the cross roof aluminum square tubing --
ours is a single 7/16 rail running aft to stern on each side
supported on 1/4 points ...
seems to be factory as the fasteners do not show through the flocking on the
inside of the pop top

as always my amazement continues ... a mass produced vehicle -- yet rarely
do we see two alike

There are two kinds of jobs in the world:
Picking up garbage and telling people things.
Successful people do both, with the same good attitude. (riw)
