While blogs are a great way to get content posted quickly and easily, actual websites tend to provide a much more permanent record - though they are a bit more difficult to keep up to date. Those of you that access my blog directly (through http://blog.thevalleylocal.net) may not know that I have a website dedicated to the Valley Line as well at http://www.thevalleylocal.net . That's where I "archive" the information that I've distilled and want to be sure and keep, posts that require more permanence, etc.
Perhaps most importantly, the website makes it easy to access this more permanent material - and it's also where you'll find a (rough) trackplan and layout tour.
So if you haven't already, be sure to browse around the website. The "About" link is much more detailed than what Blogger provides and - better than that - you can get ready access to the most important info about the railroad as it evolves from blog postings to archived articles.
