Not sure which side of DC you are on but there is a beekeeper's club in Southern Maryland which meets every other month at the library in Charlotte Hall. Very active, very educational, and very interested in helping new beekeepers. Members range from Walter with 47 years (and 1,000 plus hives) of professional experience to those of us who were "born yesterday" as beekeepers.
Yearly membership is an outrageous $5.00, but the information available is priceless. If you are not too far away for 5 or 6 trips a year, send me a pm to my email address on my profile page and I'll get you the information about the club.
