I just set up an aggregator page for the RSS feeds I will be using on my trip. Michaelb1.com has a feed for my road trip flickr set, my Google Maps route, my "Tweets" from the road, as well as the blog posts on this site. There's even a flickr slide show to watch.
I hope it passes the mom test. It has to be simple and informative. Anything less and she doesn't want to see it.
