This postcard arrives courtesy of Postcrossing. The sender writes simply “There is something magical about it; you leave as one person and return completely different.” - K.D. Wiggen.
I can’t say that I recognize the quote, nor the quoted (maybe it’s Kate Douglas Wiggin? - what a delicious connection to San Francisco!), but it’s a great sentiment all the same! I’ve never visited Arizona, but it’s certainly on my list.
