Same here. Must be a statewide thing. I'm in a very rural county. All addresses in the country (that are outside city limits, of which there are like, 4 in the while county) are simply miles from 1st and Main in the county seat. Ie. Address 2156 is 21.5 miles from the county seat. Also, odds are on one side, evens on the other. (But that is probably standard.)
And they skip numbers when assigning addresses so there is room to put in new ones, in order. So in the 2150 block there might be 2 homes, but numbered 2152 and 2156. That way they can always stick more in if they need to and still be in numerical order.
What is really nice is, in my fire district, folks get the signs through us. And we help put then up. The are blue on one side and green on the other. So if you see a blue sign, the numbers are getting bigger and you are heading away from town. Green, getting smaller and going towards town.
And since I know my station location in reference to the seat, I know almost exactly how far I'll be driving when I hear the address on the page.
