The problem with a blog, or any web site for that matter, is that you cannot access it without an Internet connection. You cannot access it if it is blocked for any reason either.
I regularly buy PC Plus magazine. It is available from newsagents in the UK. For those of you from elsewhere in the world, you can go to www.pcplus.co.uk and click on the Subscribe tab to have it sent to you.
In the May 2010 issue, I read an article explaining how to download web sites. I then went to http://www.httrack.com/ and downloaded and installed the software. The software is easy to use and the site has documentation in case you get stuck. I used it to download a copy of this blog. It took around 10 minutes and used 120 megabytes of disk space.
The software seems to have done its job and the copy appears to contain all my blog posts. I will be checking it carefully and will update this post with my findings in due course. I then hope to repeat the process from time to time, possibly each time I have added 10 new posts to the blog. Then I can copy the blog onto a USB stick so that I can view it anywhere. The screen prints below show part of the downloaded blog (click to enlarge them and bring them into focus):
