I just reviewed the pic's I took at autumn last year & the date was the 11th of May.
It starts getting very cold up here at night from here on in, which turns the trees.
There are the orchards that turn too...especially the persimmon trees...amazing orange, rust & reds.
So we could probably make a tentative date for a shoot/meet on April 30, May 1st, 7th or 8th...after that too many leaves will probably be dropped particularly if it starts blowing.
I will keep an eye on the trees up here as they turn. We can go into the botanical gardens (aprox $4 from memory) & the golf course is pretty amazing too.
Just got work out what the best time of day would be. If you want mist then there is plenty before the sun is up, swirling around in the valley's.
There are also some natural granite watering holes up here with water flowing around that ppl may find interesting...need sturdy shoes...steep.
