I have a large red fir that's been a staple on the property. I'm starting to worry about it, as the pitch is oozing on one side. I've heard that makes them vulnerable to damage, and so it will fall on my house if so. Here are a few pics. I need some advice if this is in danger of falling prematurely, I had a red fir drop just this past week so I'm getting more concerned. Fyi it's a big ****er...
