From the start you can either use the local Mifflin ridge or the one further to the south. The
former might be easier as it leaves you more of a downwind run towards TP1.
From leaving the ridge on the way to TP1,
there is a long downwind jump to Selinsgrove. Ideally you want enough height to get
around Selinsgrove and return crosswind to the safety of the ridge, so take a thermal to get enough
height.
After turning Selinsgrove, aim for the nearby ridge which is initially poorly defined
but improves as you head
west.
The ridge can carry you all the way to Orbisonia, but now you have the big problem of jumping back
upwind to return to Mifflin. Stay on the ridge until you find a thermal lifting you high enough to
fly upwind onto the local Mifflin ridge, and then use that to get home.
