Sean,
Therein lies the difference. Who cares if the course has houses protruding? What does that have to do with the decision to walk? Golf=walking, so what do houses have to do with the decision?
Also, if a course allows walking, I don't care if it's the same price to ride. I'm just glad they're letting me walk. Taking a cart would only make the round worse anyways, so why would I want to take it? I'd pay extra to walk, which brings me to.....courses where the option is walk w/caddies or cart it, taking a caddie is far more expensive than taking a cart. Though I couldn't have this option on a home course, I'd go broke.
You don't like walking through the waste areas at TR? Guess you wouldn't like playing Pine Valley, either. I can think of several other great courses with lots of waste areas also.
Scott--Your new home at Olde Liberty is not exactly a walkers course either.
You're right, it is not a good walking course, and it's worse for the wife and kids (the sizable ravines required to hit over were also terrible for the wife and kids), so that's why I'm no longer a member there. I did walk the 5+ rounds I played there. My new club has an additional 9-hole walking-only family course perfect for them. The main course isn't a great walking course, but it's not as bad as you might think, since you can cut a few of the walks down by crossing the road instead of taking the tunnels. A lot more money, though. It was a big decision.
