Every time we go out to the property in preparation for building the house, Adam immediately jumps onto the riding lawnmower (his "quad", lol) and rides all over the area. It's pretty rural, so he drives all over the place out there. Randy says it's the best $$ he's ever spent (we bought it used just for this purpose...I wonder if it actually mows??).
Now that we've leveled the ground, there is a ton of dirt for him to create dust-devils with and he just can't get enough!
If you look closely, you can see that he's actually covered in a thick layer of dust. ;0)

I used Melyssa Connolly's AWESOME kits:
"All Boy"
"Critter Tags"
"Pocket Critters"
