Maximum printing resolution

So how big is the maximum print size for an 8 Megapixel image? The reason I pondered this was two experiences. Someone I know flew around the world in a small plane, a home-built Vans RV aircraft. I took a photo of him getting out of the plane with my Canon Digital Rebel XT. I then blew that photo up to 36x24 inches as a poster. It looked really good. (around 100 DPI)

Recently, I enlarged a photo I took of the Pigeon Point Lighthouse similar to the one to the left, but from the ocean side. I blew it up to 22x28 inches (around 200 DPI) and I really could not see any problems.

I knew I had to blow the image up fairly large or the detail would get lost. It looked great. And it only cost 25.00 at a photo shop.

So I'm not so sure that the standard of 300 DPI is valid anymore. Yes, that gets you a gret resolution, but at what advantage?
