Saturday morning we took the kids to a really cool obstacle course. But first, a few random photos from the trip there.
Here's Lisa just down the street from Yumiko's Mom's house.

Yes, this is actually a fairly normal-sized street for a residential area like this. Yes, it's a street for cars:

Yes, trucks do drive down it, too. (I wish I had a shot of a garbage barreling down the road without hardly slowing down, but when that happens, I'm usually too busy jumping out of the way.) And no, it's not one-way, and yes, I have seen cars pass each other on this road. Pretty cool. (The street is about 8 feet wide in the narrow spots. The main road near her house [two lanes, plus cars parked on the sides against the curbs] is about 20 feet wide.)
If streets are this narrow, you may wonder how people park their cars. The answer is, very close to each other:

Technically, they're overlapping, since the mirror for the second truck is extending forward past the back of the first. You can't see it very well in this shrunk-down photo, but these are actually parked up on the sidewalk area. The tires are about a half-inch from the drop-off of the curb, and on the opposite side they are maybe two inches from the planter. I have another really cool parking picture, but it will have to come later when I find it.
Of course, since streets are really crowded for cars, many people ride bicycles, and park them in places like this:

Since land is at a premium, people want to build on every square inch of their lots, even if it's a weird-shaped parcel of land.

The close wall of this building is maybe 18 inches wide.
This is just a random shot of a typical neighborhood, taken from the train on the way.

By the way, I used Google maps to compare our neighborhood with Yumiko's Mom's, and then I went around and counted buildings. It turns out that in the same space as our yard (admittedly larger than average for Boise), there is one retail store (a 7-11), three or four other businesses, two or three commercial parking lots, and somewhere between 170 and 200 standalone houses and apartment units. This is on Yumiko's Mom's block, which doesn't have any very big apartment buildings. (See the photo of Lisa above that started this post. Most of Yumiko's Mom's block is like what you see on the right and left sides of the street. The big building at the end of the street [21 stories] wasn't part of what I counted.) Obviously the population density would be a lot higher if there were a 40-story apartment building like this one from near her house:

Okay, enough of that for now. Anyway, we finally made it to the really cool obstacle course. There were 45 different stations. Here is a sampling of a few of them:
We had fun. :)
