We will be celebrating our 20th anniversary in mid October it would like to go somewhere in the US. We’ve been to Hawaii a number of times and have been up and down the west coast (we live in the Bay Area). We enjoy spending time in nature, dining, art/culture and maybe a spa day. We are not snow people and only so-so on the desert. Mountains and lakes sound nice and maybe some fall color. Want to avoid snow- so not sure where that would limit us to they time of year. Was considering Colorado or Salt Lake City area…but open to any and all suggestions!
