If i had one of those covered containers, I would have saved a life!
This summer, we washed a house with a pretty good sized fish pond near the home. I covered the pond to keep the x-jet's overspray out of it......
The pond was close enough to the home that we had to stand right next to the pond in order to properly spray the house. A frog jumped out of the pond and right into our bucket of cleaner...........and prompty died. One of those moments that's both sad and funny at the same time.......
