A story behind the story
I mentioned that the pictures of the cattle were taken on "FM 730", the standard short designation for Texas Farm-to-Market Road 730.
The Farm to Market roads, and their counterparts in the western portion of the state (mostly), the Ranch to Market roads, are an interesting part of the Texas highway system. They are secondary roads built and maintained by the state under a program instituted in 1937 and fully formalized in 1949, and were originally intended to allow farmers and ranchers to bring their products to market (although interestingly enough, the first one actually designated a Farm-to Market Road, built in 1941, ran to a sawmill).
These roads today constitute over half the total road mileage of the Texas state highway system.
There are some interesting matters of notation for these roads. Although the formal names of the roads are Farm to Market Road ## or Ranch to Market Road ##, for conciseness the signs say "Farm Road" or "Ranch Road" plus the number.

But when these roads are referred to on guide signs (showing, for example, the distance to an upcoming junction with one of the roads), or in other formal references, their designations are presented as "F.M. 730" or "R.M. 2588"; "FM 730" is a common form in written material. And they are often spoken of orally or in informal journalism as "Farm Road 730" or "Ranch Road 2588".
In fact, there is only one state road in Texas whose entire formal name is "Ranch Road so-and-so", and that is Ranch Road 1, near the former ranch home of President Lyndon B. Johnson (in Perdenales, Texas, pronounced "pay-der-NAL-ayss").
Another interesting thing about highway notation in Texas is that, until quite recently, interstate highways were always spoken of, and mentioned on guide signs, as "IH-20", not as "I-20", as is common elsewhere. Of course this convention is certainly understandable, since the name of that road is "Interstate Highway 20". And of course, never as "the 20", as would be done in California ("his shop is somewhere over on the 405").
