It's good to have a hobby.
I guess it's cheaper than collecting stamps.
I recently spent several weeks in Florida State Parks.
Every morning, the dog owners go for a walk. In one hand is a leash and in the other, plastic gloved, is a little black plastic bag. When the dog finally sniffs out the correct spot, the deposit is picked up with the gloved hand and placed in the bag. In at least one instance, there was also a moistened wipe for ....you know.
In several, at the sewage dump stations, the bags were provided. That is, the fee or perhaps florida taxpayers are providing doggie poop bags.
Think then about Walmart and the 50 pound bags of dog food. All that goes in comes out.
