I've had some distractions, but I'll get back to the mods to the level detector in the next 36 hours. Then I want to try a big change to the way the sections are laid out, so I'll put a new example together. I'll need to buy more of some parts, web-order.
What you call roundabouts are either true roundabouts or traffic circles. A traffic circle has traffic already in the circle yield. A roundabout has the yield on entry. We've been slow in going to roundabouts.
Note that every region has its own traffic patterns. In New Jersey, for example, many roads have left and U turns from the right lane, via ramps called jughandles (because they look like it). There are different lingos for roads, too: freeway, expressway, parkway.
Off-ramps are also called exit ramps.
Don't know if the Pac NW has any SPUIs. (Look it up on Wikipedia.)
It is very illegal to pass a schoolbus stopped with its red lights flashing. In many areas a similar law requires you to stop when an ice cream truck has its stop sign swung out. Unless there is a sign forbidding it, you can turn right on red after a full stop. (Except in NYC, where it's occasionally permitted by sign.)
In many cases the cheapest pharmacies are in the supermarkets. If the places you shop offer discount card/tags, get them. They can save you a bunch, but you'll have to put up with a bit more junk mail. If you need a prescription specially compounded, the chains and supermarkets can do simple stuff (like flavoring) but you'll need a specialty pharmacy for anything else.
If your area is blighted by a chain called White Castle, stay away. The food won't make you sick but the oddities of the, er, cuisine may/put you off your feed.
Find out what station carries Mariners games. There may be one or two more afternoon spring training games on the radio.
