The Bumble on Seneca Creek Park-Smokey Glen Farm map near Gaithersburg, MD. I did the Green course, which meant visiting 3 of the 5 windows (each with 5 controls, all of which must be visited before proceeding to the next window), plus mandatory first and last controls. A sunny day, but cold with temperatures in the upper 20s and breezy.
The course was very similar to the course two years ago, using the same windows with (slightly) different control placements. So I didn't just cover the same terrain as two years ago, I chose to visit the window SW of the central window rather than the on to the NE, using the power line and road route through the housing development to connect my 2nd and 3rd windows. Control order: 1-MLKON-FHGIJ-STRQP-27.
Route Gadget.Hit all the controls pretty well and was in contact the whole time. It may have been a little quicker to do the first window in the order OMLKN. I think I got the other two windows right. Visibility was excellent and the vegetation is very accurately mapped. Some of the vegetation is sharp, so there was some bloodshed.
