Biggyfoot - all photos, fake

yeti- footprints in the Himalayas, fake

Nessie - faked with a toy submarine, scientists have dregged the loch and recovered nothing( and shes supposed to be 20'-30' long)

Don't get me wrong, anything is possible, but when every person comes forward with "real" photos or film it turns out to be manufactured. reb you're right, it is great to imagine, but its just like religion. Its all about faith.
