It was quite windy yesterday - 20 gusting 35. I'd be interested to hear if this had anything to do with it, particularly close to the hangar.
Interesting thought. Wondering about tail rotor authority margins on the 120? As has been pointed out here by many, some helicopters have plenty and some not quite enough.
It is often said of these situations that "there are those who have and those who will." The goal is to remain in the latter category as long as possible. With this in mind, and as a relative newbie to helicopters, I have established a "personal minimum" of 25 kts peak wind as one no go criteria, at least for awhile (without an instructor on board).
