Have you heard of the tourist jeep trains and jeep tours? I just came across a website that seems to collect the post cards of the many 1950s and 60s tourist jeep things

Fairchild Gardens, Coral Gables Florida it seems.

The landscape architect who designed Fairchild was William Lyman Phillips who obtained his landscape architecture degree from Harvard in 1910.

His incredible talents landed a position with the highly regarded landscape architecture firm of Olmsted Bothers. At his young age he began a long association with Frederick Law Olmsted, one of the outstanding landscape architects in America. (which I posted about, as crazy as that sounds https://justacarguy.blogspot.com/2017/05/a-park-over-freeway-in-seattle-thats.html )

 In the ensuing years, Phillips worked in the Panama Canal Zone, Puerto Rico, France, Italy, Switzerland and Germany. Phillips came to Florida in 1924. In 1933, he started working with the Dade County Park Department and drew plans for Greynolds Park and Matheson Hammock Park.

Florida seems to have been a tourist destination for as long as there've been interstates and airports to get the tourists delivered

and saving the best for last.... a Jeep tour INSIDE a cave!

Notice that they upgraded to a newer Jeep that seems to have a natural gas fuel system, no doubt the exhuast gasses were upsetting customers
