helimark / notar fan: what i cannot understand is why the border patrol has not elected to have a mixed fleet of as 350 / md 530f. after visiting or working at most of the usbp sectors, the statement i hear so often is just give us new 500 for the " in the dirt" ops and some astars for the heavier/higher ops and all would be good in the world. as an outside observer seems to me to be the logical solution.
