T his cat on crap-book had bought a "rolling plant caddy" and set his 14"WSM in it. looked pretty cool but not big enough for an 18". I got to thinking, and that's dangerous itself, of going to the orange store and buying 4 locking casters and attempting the mod. I really don't need to move mine much, as sits under my covered porch. I tried a search here for WSM rolling mod, but didn't get much in the results. Anybody got pics? A 20" rolling plant caddy is about $60, but I think I could do it for less and not make it as tipsy. Thoughts?
