Monarch Butterflies

You will enjoy it.
I make this same post every year. When we went in the middle of a February one year, it was during the week and not with a tour. We were on the mountain at 8 a.m. and it was cold enough to see your breath. The four of us walked up the path to the peak. As the sun hit the trees, the first layer of butterflies started stretching their wings in anticipation of flight. As each layer warmed up and took off, the tree branches gently lifted themselves.
The butterflies kept landing on me and we walked, in total silence, except for the sighing of the wind and the sound of a billion butterflies beating their wings.
It was the most spiritual experience that I've ever had.

Don't wait too long Neil. IMHO, it is one of the wonders of the world and their habitat is being encroached upon by logging and climate change. You might want to move it a little higher on your bucket list.

Do it Neil! They may be reduced even more the next year. It will still be spectacular. You can always make the trip again if you hear that there will be a greater than 25% increase for any particular year.
