Narrative:

I have flown into the dc area many times and know how busy the traffic area is, so I planned to land at jyo to avoid the congestion of the main dc airports. I failed to check NOTAMS when getting the WX. I will be careful to check NOTAMS in the future. I landed at jyo airport without a squawk code. I didn't check the NOTAM which required a discrete transponder code for landing within the washington dc traffic area. I didn't know about the surface to 18000 ft space restr of fdc NOTAM 3/2126 for ZDC. I will be careful to check NOTAMS in the future.
