I imagine a riding lawn mower would discourage one from stopping and going,
bigger area, etc. could take all day. ;o) ~ jan

The toads do head for safer ground than the yard (Ours is about 2
acres...cut by riding mower). The garden has lots of toads; the beds around
the house have lots. The neighbors have lots. A whole army of them hang
out by the back door light for their evening meal...they think it is an
all-you-can-eat food place. Sadly, some do get chopped in the mowing.
