Strange things are afoot

You can't really tell by this first picture, but when I mow the lawn, I put all the grass in the back of the truck. Someone came along and put neat little rows of grass in various places on the truck, flipped up the wipers and put the tailgate down.

Next thing, we woke up one Sunday morning to find this tent on our lawn. There was a sleeping bag inside and beer cans (empty) too bad, all over the lawn.

This morning I found these ornaments on our lawn with a card. The card reads " We are the travelling ornies of conception and good luck. We come in peace. Please help us bless more families by passing us on to another yard ".

We are pretty sure we know who did the first two things, but this last one, I have never seen anything like it. I was hoping to keep them, but alas, I guess we should pass them on. Have a great day all.
