Today I tore up the back sidewalk... With a pick axe (which is an awesome tool btw). The sidewalk was asphalt, but wasn't installed correctly, so it wasn't too hard to tear up. Most pieces came up in smaller 4"ish pieces, but toward the garage they came up in huge huge pieces (like 2'x2' or larger).
Unfortunately it was wicked hot and humid this weekend, so I'd work for like a half hour and then have to go inside and rest for awhile. It took me all day to tear up the sidewalk (all that's left is the little bit between the lean-to and garage), which is about 32 feet long (not including between the lean-to and garage).
