Badgers are not uncommon around Loch Ness but they are
rarely seen by daytime visitors to the area. One of the more interesting
aspects of "Loch Ness Investigation" lies in trying to understand what
some of the witnesses may have seen when they thought they were seeing a
"monster". This approach is different from the usual question of whether the
witnesses were telling the truth or lying, and aims to offer the widest possible
range of candidate phenomena.

Here is one I recorded in infrared mode just 100 metres from the shore of Loch Ness. While there are probably no tunnels under Loch Ness, there are quite a few on the shoreline.
