Out of control fire....

If that's what the vegetation is like all the way around your house, I'd say you're pretty safe.
That's where I mowed this spring. Sadly thanks to numerous disasters I never got the rest of it mowed. We have a rather dense area of trees that I have been thinning out over the last several winters...but it still needs a ton of work. Directly across the road is an open field..the vegetation is knee deep clear down to the lake...east of us is an un-mowed parcel that is knee deep...and littered with dead trees...
