There is a sign that says R/C Flying Field on lake Murray Drive right after the park ranger's office.  Follow this road approximately 4 miles.  You will go past the field trial area and the trailer house (Park Ranger lives there).  You will come upon a dirt road that exits off the paved road to the right.  There will be a sign there that says "LEM ROBERTS ROAD - RC FLYING FIELD".  Take this dirt road to your right.  Follow the dirt road about a 1/2 mile and you will come upon another dirt/gravel road that exits to your right.  You will see our covered area and our field right there on your right.  Please see map below for reference.  Click HERE for a full blown map of Lake Murray that also shows the R/C Flying Field location.
