I would agree with Cowboydoc and Bird, but I would still tell you to be carefull on any hill particularly if there is grass or other material that might produce liquids under your tires. On a steep enough hill you might not rool over but you can slide, and that can be just as interesting, producing it's own pucker factor.By the way confrats on selecting the machine.
