Phil has some valid points. The SNIRT is usually well attended, especially in recent years with the lack of snow. Lots of snow makes people stay away. Of course there are idiots that appear whenever you have large groups of people in one place. We've seen some truly amazing things, both good and bad!
But after a long winter, the SNIRT is good fun and you meet tons of people, see some sick machines, watch people get hopelessly stuck, swamped, and sometimes yes it makes you wonder what the heck they were thinking, and find yourself surprised that they make it through some of the stuff they get themselves into.
There are usually a couple playgrounds where people congregate to watch others play in the mud, it's like a party with a couple hundred close friends. It is fun. I have done it for the past 6 years and have seen 10,000 machines on the hill, and have seen a couple hundred or a thousand other years. Like anything, the run is what you choose to make of it. If you go looking to ride alone and coast down easy trails then yeah, you might think twice. If you want to hang out and ride with people, watch people play, and enjoy a long day's riding then give it a shot. I think you will be glad you did.
