hi,
just going through some old posts and came across this one.
very interesting in the numbers, numbers said about the calls they had especially in 98-99 (48)
I did some digging and this brigade was called Wattle Range before it was re named Mt. Graham.
It was about the same time that the W Range support brigade was formed, thus i suspect that many of the 48 calls were actually "jobs" that the WR support brigade did and not the Wattle Range / Mt Graham brigade. (would go for the average of 2-3 per year as much closer to the mark)
