Skating rinks have smooth ice. What if there's bumpy frozen slush like there
now in 80% of the back roads in the Northeast? Sliding won't be an issue
where damage to the tire/gear may be a consideration.

If the ground is that rough, you won't be going fast enough for the flaps to make
any difference. At the same time, however, you risk damage to the flaps in low
wing aircraft and loss of control due to gusts in high wing aircraft.
