Rain barrel

I love it when an experiment works. A tarp attached to my cabin has almost half way filled my 55 gallon barrel. It only rained for maybe 7 hours. It's not even raining that hard. I know if I actually used gutters it would be better. But gutters cost money and I already had the tarp. I have (4) 15 gallon barrels to fill next. I also have my former beer tub aka bath tub to fill up too. Going to hang more tarps around the cabin.
