sap from large pine tree
This is my second spring in my southeast Denver home. I have a very large pine (not a blue spruce) next to my deck, and it's dropping much more sap than it did last year. My questions are: 1. Is the tree OK? It has new growth and looks great. 2. Will this sap problem stop soon? Thanks!

If you are seeing increased sap from the tree, it could be a sign that there are pests on the tree. As a precaution, I would treat the tree with a insecticide to deal with any possible pest infestation.
The increased sap could also be from stress. A very wet or dry spring may have brought it on.
The sap should return to normal either when the pests are dealt with or the seasonal stress is gone, which ever was the cause.
