A rainy day activity

[B~C]

to help keep you from going nuts (it it's not to late).
put on your best running shoes and go to your nearest golf course. In the parking lot, stretch and warm up. When properly warmed up, sprint out onto the driving range and harvest a few golf balls (the more folks using the driving range, the quicker you must move).
After harvesting a few golf balls, find a nice long dock line, I bought a 3/8 x 25', and tie a monkey fist in the end...what the hell is a monkey fist? this tells you how to tie one http://www.igkt.net/beginners/monkeys-fist.html
Stick the golf ball in the center of the monkey and tighten knot.

You now have a dock line you can hurl at the dock and possibly catch a cleat...of maybe smack Mike in the noggin

The golf ball is just a wee bit large so I managed to waste several hours whittling it down for a better fit
