Aliasing side_walk → sidewalk
Link to alias
Reason:
Same thing.
Wikipedia article is at https://en.wikipedia.org/wiki/Sidewalk
"A sidewalk ... is a path along the side of a road."
Three uploads currently tagged with "side_walk",
I imagine occasional new upload will also get tagged with "side_walk".
EDIT: The tag alias side_walk -> sidewalk (forum #230935) has been approved by @bitWolfy.
