a little bit 18th century, a little bit 24th century
A simple but clever idea: put a camera in a bucket of water. I'm a little disappointed that no cats came to drink but I love this anyway.
if they ever make game cameras cheap enough I'm tempted to get one just to see what critters roam through my backyard.
Of course it depends on what you consider cheap enough but a quick look at Amazon I saw one for $49 and another for $36.
