Caution—Do Not Dig
The fact that this huge concrete cube has the words “CAUTION—DO NOT DIG” makes most people even more curious about what’s buried underneath. Is there buried treasure down there? Maybe this is where they buried the body of Jimmy Hoffa. Well, actually, it’s none of those things. The words that follow warn of radioactive material from the 1940s buried down here. So, anyone who starts digging in this area will get an unhealthy dose of radiation poisoning.
