This evening I walked to Parque Santa Ana, about 5 blocks from my apartment, as each weekend evening there is music, dancing, and food and craft vendors. As it turned out there was no dancing but there was a concert of Christmas carols in sign language. It seemed to me that the performance was by students and staff of a school for the deaf, but that is only an assumption.
None-the-less it was impressive and I was amazed at the numbers of folks in the audience who signed along with the songs.
Looming over the park is the communications tower you can see in this, not so good, photo that has been decorated for Christmas.
