Most likely would be less of a burden if left to them that knows.
If your Old Boots really mean that much to you, or have some

Heck, my Neighbor, last year tried to re-roof his own Garage,
even rented a hot tar pot to do it. WELL ~~~~~~ He no longer
has a Garage to even worry about! (guess you know what happened)
I was just curious is all, >>>>>>>
But Hey ~~~ What do I know ?
