JUST DUCKY: After much confusion last year, public duck hunting off the Potomac's Virginia shore below Wilson Bridge this year will be run by Virginia's Department of Game and Inland Fisheries, which has designated eight sites in the river for floating blinds.

The sites are marked by stakes with numbers on them; four are above Belle Haven Marina at the mouth of the Hunting Creek embayment; the others are below Belle Haven.

The sites will be available on a first-come, first-served basis on Mondays, Wednesdays and Fridays during duck season, which reopens in Virginia Nov. 22. Hunters must provide their own floating blinds, which must be tied to the stakes or to floating buoys the department plans to install soon.

For details on this year's plan, call Virginia officials in Fredericksburg at (703) 899-4169.
