I've had many my share also.Tons of bottles,cars,trucks,swing set in a homemade cess pool,huge sink hole from a rotted stump smack in the middle of a secondary road,abandoned oil drums,knocking out IBM's computer bank of fiber optic cables after an'' all clear'' from Dig Safely AND existing blueprints of the ''as-builts'',chicken,horse,cow bones,but my ''claim to fame'' was one mastodon skull--part of the youngest mastodon[12K years old] ever found on the planet---Hyde Park,NY,basically my backyard in 2000.That was cool. Entire skeleton of the big guy is a main attraction up at PRI's Museum of the Earth up in Ithaca,NY now.Push the button on the monitor and you will see muah on my backhoe.
