CPK - ORF210/14.3
Exit 291B off 64, 104S towards Elizabeth City, stay right. Past the Food Lion at Great Bridge Blvd, continue South on Dominion Blvd. After Cedar road, I think West Road is the 2nd left. The Airport is a few miles down West Road, on the left.
I used to commute from ORF to CPK a lot, it's about a 20 minute drive. 30 minutes between 2 and 5pm.
Another option for you is Cardinals' Pilot shop. Their main office is at the Suffolk Airport but they have taken over the office at ORF, back behind the flight planning room at Piedmont. They have a few newer 172s. I believe they still have a 150 or two at SFQ too. Suffolk is another 20 minutes or so west on 58/13/32 past PVG.
PM me if you'd like more info. I've been flying in the area since early '95.
