I had the chance to ride the Minnesota River Bottoms with Griff this past spring and had a great time, he is definitely a character and likes the more technical aspects of mountain biking. His posts are always interesting, instructive, informative and full of pictures and video.
You can follow Griff, the "Mountain Bike Geezer" by subscribing to his blog via RSS feed, e-mail or visiting Mountainbikegeezer.com. Follow him on Twitter or visit his Picasa Photo Gallery.
I found the easiest way to keep up on all of the latest content for the blogs I read is to use a RSS reader client such as Google Reader or Flipboard. These allow you to put together all of the blogs you read into one convenient place. There are a lot of RSS readers that work with desktop computers and smartphones so pick the one that best suits your needs. Soon I will bring to you another Minnesota bike blog worth reading.
