our house doesn't have gutters + I don't have the type of money to install gutters + everyone in my house is disabled where we couldn't clean gutters
but I sorta wish we had them, just for rain water collections. I put some 5 gallon buckets out where rain usually collects at the overhangs of the roof. they are now all completely full and I feel like I'm wasting good rain water that I could use later in the week when everything dries back up again.
edit: I know I can collect rainwater without gutters, just that the gutters make it more efficient. we have to go to home Depot again this week for some more plumbing repair, so maybe while I am there I might grab the supplies for a diy rain catcher.
