I recently built a 6' 3-rail privacy fence with 1x4x6 pickets on 2x3x8 rails on 4x4 posts. There is a 2" gap between the pickets and the ground, so the pickets rely on the 3 rails for support. Now I see that a couple of bottom rails have a faily large hole in them (I forgot to check every rail individually for knots). They look ok now - no sagging
- but I'm afraid they might break in time. What's the best way to reinforce these rails? Put a little 2x3 section like a band-aid above the "hole"?
