It's kind of hard to see in the picture, but the sign says
"Back-in angle parking
It's as easy as 1-2-3
1. Signal
2. Stop
3. Reverse"
Just out of curiosity, has anyone else ever seen a street sign say "it's as easy as 1-2-3!" hahahahaha.
And guess how many people are actually going to back in? On the day I took this picture, there were 5 cars parked and only 1 had backed in. We'll see what happens when Fall semester starts and all the people come back . . .
It kinda reminds me of the time Rexburg put flashing lights in the road by the crosswalk (incidentally on this same street), and apparently forgot that it snows in Rexburg. 3 guesses what happened after the first big snow when the snow plows came . . .
