I can't believe I didn't get this done earlier, but I've been running since 4:30 a.m.
Here it is, the riddle poem for today:
I'm an evergreen welcome sign
Friendly to Thor, to winter,
To visitors, both friend and foe alike
I might be plain old needles
Or dressed up with a bow
Or anything human imagination
But know, if me you see,
That you are welcome, one and all!
Who am I?
