Tip. Use US Quarter to remove the drain plug and the vent screw.
I use a big-ass flat-blade screwdriver I found on the road one day walking home from school when I was 16 (I'm 45+ now). I've had it so long that the wood handle dried out, cracked, and fell off. I've since replaced it with a old piece of Hickory.
Just thought I'd share.
