Been to the States starting in 1970 and about 150 times! Know the country quite well and love it. Family had places in Manhattten NY, San Fran and South Beach Miami. California is my favourite sate overall. Best city architecture-wise is Chicago. Fabulous in Spring and Autumn, horrid in Summer and Winter. Worst Place for me: Las Vegas.
Only MO, so don't beat me up, please!
