Sometimes it's an animal that might jump out in front of your vehicle. Around this little place here, the deer are starting to get more active, the rut will be on in a few weeks, and bucks will be chasing does all over creation paying no mind to traffic on the roadways.
Other times, it might be children you need to watch out for, playing on neighborhood streets, or running after a ball that got kicked or thrown out of the yard accidentally.
Or, it might be other drivers you have to watch out for. People texting instead of looking where they are going. People going the wrong way on freeway entrance or exit ramps. Drivers under the influence of drugs or alcohol who are endangering others with their delayed reactions and less than clear thinking or vision.
Once in a while, it is because something really great is sitting at the side of the road with a "FREE" sign attached to it. I can't begin to recall all the neat and useful items DH and/or I have picked up from the edge of some one's yard for the unbeatable price of absolutely nothing. . .
. . . a wooden dresser in perfectly usable condition if you overlooked all the graffiti scratched into it by generations of college students (presumably this was dorm furniture once upon a time). . .
. . . a bathroom vanity. . .
. . . an end table. . .
. . .and this week, a wooden rocking horse in near perfect condition!
Being in great condition, and being the perfect size for my grand kids to use, and retailing somewhere over the $75 mark brand new, it was something too good to pass up. I stopped, backed up, jumped out, and threw it into the back of my suburban feeling all the while like I had won a prize.
Yes, always keep your eyes peeled while driving. You never know what might jump out at you.
