The walk score for my house is a 5. For the most part, I don't have a problem with that. I'm out in a rural area, although I'm close to DC, Annapolis, and Baltimore. About the only thing I'd want to change, is for more of the roads to have a shoulder, at least a narrow one. Most of the streets around here are just wide enough to at least have a line down the middle, and on the sides. But, if you want to walk along the road, it's a fine balancing act between being on the pavement, and uneven ground.
I'm close to a little neighborhood park that has a basketball court, a couple of tennis courts, a playground, and a couple fields where you could play football, throw a frisbee, rumble around, etc. I could actually hop the 4-foot fence at the back of my yard to get to it, as it adjoins my property. But to get to it, proper, I'd have to walk about a half-mile.
On the subject of high-speed rail, or trains in general, ironically, I live about 1 3/4 mile from a defunct railroad line. I think it was originally called the South Shore Railroad, but I always knew it as the Washington, Baltimore & Annapolis (WB&A). My old family home was less than a quarter mile from one of its stations. I know my grandmother's cousin had memories of riding it as a kid, and my ancestors also used to go to the station to pick up supplies for their little dry-goods store.
The Washington-Baltimore branch went defunct in 1935. The Baltimore-Annapolis portion handled passenger service until the 1950's, and then switched to buses, but I think carried freight into Annapolis until the late 1960s. The South Shore branch, which went from Annapolis and cut back to intersect The Washington-Baltimore branch in Odenton, about the half-way point, I'm not sure when that shut down. It also extended out to the Pennsylvania Railroad line, and the B&O line, so I have a feeling it outlasted the Washington-Baltimore branch, at least.
I notice that public transportation seems to be getting worse, in general. When I was in high school, I used to catch the bus at the end of our street, at least until I started driving. This was near the spot of that old WB&A station from years before. Back then though, there was a Metro bus stop near where I caught the school bus. So, in those days, if you wanted to catch public transportation, it was only a 1/4 mile walk from my old house. But they took that route away, years ago. Now the nearest bus stop is about a mile away.
Where I'm at now, I don't even know where I'd go if I wanted to catch a bus. I know of one or two lots where you can park, and then catch a bus that takes you to the nearest Metro (DC's subway system), which is a 15-20 minute ride from that lot. And, that's actually not a bad deal, in my opinion. I just googled it, and now, (9:15 am) it looks like the bus parking lot is about 19 minutes away, whereas the Metro station is about 28. But traffic is light, now. If I worked in DC, I could see driving to the parking lot and taking the bus in to be a nice alternative to driving to the Metro stop during rush hour. Depending on how long I have to wait for the bus, that is.
