I don’t know if it is all over the South or not, but sledding on grassy slopes is popular in our area. Although we do occasionally get snow, the most use purchased sleds get seems to be on the grass.
A sled is not necessary though. Grass sledding can be done almost as well (if not better) just using a piece of cardboard.
The type and texture of the grass seems to aid in the slope being suited for sledding. A fine grass seems to work very well.
A fairly steep slope is an absolute must for successful sledding, though.
Kids and adults alike seem to delight in this drier (and usually warmer) version of sledding.
