Can anyone recommend a good site on how to add radiant heat to an
outside, sidewalk. I want to add a 100' side walk to my shop to keep
me out of the mud and wet grass and am interested in the pro's and
con's of heating so that I do not have to shovel.

You want to heat the outdoors, or a least a little patch of it. I hope you
have deep pockets.
