Coachella Valley is now known for the famous music festival but for over 100 years it's been known for dates. 95 percent of the US grown dates are from the Valley and about 2500 people there work in the date industry.
Date shakes are a signature drink of the area and the area farms have been attracting roadtrippers since the early 1900's with dates and shakes. Oasis Date Gardens , has a history that goes back to 1912 and their date and date shakes shakes are really some of finest around. They are famous for their medjool dates but have other varieties too. They have a sample area and a really nice cafe.
The Valley has used the dates Middle East origins in marketing through the years and businesses took on Arabian themes.
I've always liked this area of California. A lot of people settled there because of cheap land and started these unique roadside farms to attract the daytrip and weekend travelers.
