"10-16, 3-14, 11-12, 8-9, 17-18 (or 19)"
While those are some interesting progression of holes, the walk from 16 green to 3 tee is over 100 yards, 12 green to 8 tee is nearly 190 yards, and 9 green to 17 tee is about 150 yards.
Likewise, "...last week I played 16, 3-7, 13-15, 10, 11, 12, 8, 9, 17, 2, 19, 1,18 in that order"
The walk from the clubhouse to 16 tee is about 175 yards, 7 green to 13 tee about 150 yards, 12 green to 8 tee about 190 yards, and 9 green to 17 tee 150 yards.
Clearly, some of Flynn's routing at Lehigh works well as sets of holes within the 18/19. But the above two routing iterations are a bit disjointed.
By the way, Bill, who designed and/or built the 19th hole and when?
