I just blogged below about our ride-a-thon but it is out of order so you'll have to scroll down to "Rivers Edge Ride-a-thon" title to start at the beginning. I tried, but it messed up...or I did. Either way...there is an order to the story :)

Also here is a link to see pics of Sierra's new (used) tack.
