Thank you everyone for the information. It sounds very interesting and
worth a trip.

On the subject of hummers, we have 3 juvenile Rufous in our yard. Yesterday
they were roaring around chasing each other and nearly ran into me. I had
the sprinkler on and one of them loves taking a shower. He sat on an
antenna wire and let the water shower him while he ruffled his feathers.
Very cute. When I moved the sprinkler away from the wire later to another
location he came back and hovered in the water.

They are very frisky and playful. They are not the least bit afraid of me.
They love to sit on stakes in my garden and I can walk right up to them.
