San Diego??
You are living in my dream location. The wife and I went there in the 90's. She was on a business trip and I went along to give her moral encouragement
The best part of SD is the weather. In my next life I'm coming back as a weather forecaster in SD. Low of 67, high of 72 and sunny - repeat as often as necessary.
I did take the tram to Tijuana. I purchased two amazing blankets for maybe 10.00 US?? at the time (I know they were cheap). I do remember always looking over my shoulder. There were always pickup trucks with 4 federales riding in the back with their rifles displayed. It was a very unsafe place to be.
I stopped in one of the local joints, had a beer, and left as quick as I could.
Woof.
