Yah, road slush is not too fun to walk in. Especially when cars go by!
Many of the houses around where I live dug little channels in the snow along the curb to help with draining.
Just thought I would add a picture of the snowman I made after he started to melt:

I don't know how the head managed to stay on for as long as it did! He was vertical when we started.
Can't wait until the expedition!
