With the help of my much-smarter-than-I-am niece, I’m setting up links to show the actual roads I’ve taken. The 1st is from Fl., to the 1st corner, San Ysidro, CA, and then over to Lake Tahoe. Hopefully, others will soon follow!

OK – I can’t get the hyperlink to work so you’ll have to do a copy & paste.
