Thanks, Ron. I'll call you in the morning to arrange to meet you somewhere this week. (I no longer live on the road you used to walk uphill to your house.) My number is 314 132 4396, although I don't live in Colima.

And thanks to everyone else for their good ideas. This friend in Ohio, an incredible musician in his early fifties, is bedridden now with an incurable illness. I could send him a postcard once a month, and I could also send some to my elderly aunts and an older friend who just moved into a nursing home. Tomorrow will be Postcard Day.
