We have been using Adamz K9 waste cleanup since March 2008 and have never had a single problem. This years snow was a pain, but they trudged through to my back yard and chiseled out the stuff and did a super clean when it all melted.
I also messed with the sidebar a bit. Moved stuff around and added a local places I like ad space. I am not making any money off the places I put there, just want to spread the word. Will work on making the ads better. Right now there are two and they are both sideways.
