The Famous Joke in Google SEO World
Where's the best place to hide a dead body?
The best place to hide a dead body is page 2 of Google search
UK they come and do road works in shifts. You need to wait for the people to finish digging the hole, the other team to do the job and then before the last team returns to fill the hole back up (normally a 72hour window) you can place the body there cover with cement and ruble the fill in crew won't check or question and just fill it back up.
Works more so for road works than gas / water line repair.
