[Geysers] Grand interval is changing?

[Paul Strasser]

I beg your pardon re your aunt's memory, but the 5-6 hour intervals were
indeed unprecedented.   And not just the short intervals but the astonishing
reegularity were both unique.

What is interesting is I was talking to my aunt about this. Many of you know
her as Jeannine Wagner (Montgomery). She was pointing out that this is not
unheard of for Grand, but the average has been so long at 7-9 hours it is
what most remember. There was a couple years - around when I was born, that
she remembers it having this happen, but it was short lived. We should watch
to see if this lasts more than six months or is just a short lived thing. 
I am curious myself though. Lots of interesting things going on. Also
welcome back Plume. It was so weird being there in September and not seeing
it on Geyser Hill.
