I was going to post a work pic today but the glare from the sun was too harsh and it didn't come out, so the sign couldn't be read. But what the heck, this is something I've wanted to complain about in a public forum for a long time so here goes.
The sign which I attempted to photograph is at the intersection of Iowa and S. Mesquite streets. It says that the block numbers for that part of Iowa are 600 to the east and 500 to the west.
It's wrong. It should say that the block numbers are 500 to the east and 400 to the west.
Based on my experience over the past several years--and particularly when I had a job delivering final cutoff notices for the local electric & gas utility--I can say with some confidence that a good 1/3 of these block number signs are wrong. They are either: 1) on the wrong block, 2) facing the wrong direction, or 3) both.
This is probably not something that most people will ever notice, unless you have a job that entails knowing exactly where you are at all times.
After making more wrong turns than I can remember from looking at these signs, I quit paying attention to them except as a rough guide for an approximate idea of where I might be on any given street. If you really want to know which block you're on, you have to look at the house/building addresses.
If you don't believe me, just start paying attention to them as you drive around. I'm quite certain that you will eventually be dumbfounded at how inept the city of S.A. is at the seemingly simple task of putting up street signs.
