My back aches in sympathy for you!
...but dang, that looks NICE!!
I'm sure you increased the value of your home by much, much more than $1300 and the cost of the new flooring. Good job!!
If crime ever decides to take a break (yeah, like that's ever going to happen), I'll pay you $1300 to come to my house and install more flooring.
.....Knock it off - I can hear that groan from here!!
