This was the METAR on offer for our departure from KBDR:
KBDR 161952Z 09005KT 10SM OVC005 07/04 A3013 ...Wind out of the east at five knots, good visibility and a low overcast. We took off from Runway 6 and entered the base of the cloud layer at 500 feet, as advertised, then emerged from the tops at 2,400 feet into bright sunshine. And that was the last cloud we saw for quite some time.

Would I have been able to complete a visual approach without any problem? In all likelihood, yes. Was asking for the RNAV approach the conservative thing to do? You bet!
