Sometimes I go out and massage them out with the torch on the cooler 35 36° days where it will never thaw unless you do.
Yes, that happens occasionally in some spots. Our larger problem is that about 1/2 our taps in our main bush (so maybe 1,400 taps) run through a small culvert under the road where it's pretty flat. Inevitably there are freeze-ups there. The dry line helps deal with that most of the time, but it's been an issue the entire time I've been around.
