... They’ve got a hodge-podge for their coat of arms;
The arms have a bridge and a Spanish cathedral
And seven flags to display all their charms.
Hmm, that scans almost as well as the original Marty Robbins song, "[Out in the West Texas Town of] El Paso". But Laredo, Texas is not out in west Texas, it's down south. In fact, if I left my house and got onto I-35 and headed due south and slightly west through Austin and San Antonio, in a little over six hours (according to Yahoo! Maps) I'd come to Laredo, down on the border with Mexico. (For those of you not all that familiar with my home state, Texas really is very large. My favorite example is that when you are driving west on I-10 leaving Louisiana and enter the state of Texas, there is a sign there that tells you how far it is to El Paso (in westernmost Texas) and Los Angeles (on the Pacific coast of the North American continent). El Paso is halfway to Los Angeles. But I digress.)
In any case, it's a truly amazing "coat of arms"/logo.
* Yes, I know that saying "Rio Grande River" is like saying "big river river". But so is saying "Mississippi River"; Mississippi means "big river", too. Apparently, there are a lot of "big rivers" in this country. ;-^)
