in the summer of 85' I worked for the highway department, we planted over 700k new palm trees that summer. I think, or should say know, a lot bit the dust due to drought, many were planted in places that a few years later took them out and some are still there.
They never went back to allowing lines of palm trees to be planted along roads due to traffic accidents. it was a damm curse in the valley to run off a road a lot of folks were killed over the years running into palm trees. I had several friends that were.
For sure the valley landscape has changed radically, it was pretty cool in the 70's and through to the 80's, but that freeze in 83 changed the valley big time. The palms we planted were a mix of types all mainly shorter ones that were freeze resistant, but I think the dry weather got a bunch of them. We did plant some Washingtonians, or whatever they are, but only around Harlingen and some into Browntown. Planting along the right away was a wild deal, as there were so many buried , and never permitted, electrical and gas lines that it was a constant adventure.
