As promised, I cleaned off my patio today. I wish I'd thought to take a before (or after, for that matter) photo. I organized all of our sand and water toys and cleaned everything. By the time I was done, we were all soaking wet.
But I got rid of 44 items:
A few things I had to trash, but most of them are going in a bin of things I'm planning to sell at an imminent garage sale. If the garage sale doesn't happen in the next few weeks, I'll just donate or trash the items, depending on their condition.
I feel much better now that this job is done.
