Take a longboat with 26 of your best men! Sail to where the sun sets; there, you will find a village. Pillage, plunder, and burn everything you find!
Oh wait...
Honestly, I'd suggest these things:
- Read novels; I got tons of Forgotten Realms books I have yet to read, including R.A. Salvatore's "Promise of the Witch King" that I got for Christmas. I have little doubt you have novels you would like out there, fiction or not.
- Listen to music; Your taste and mine may vary, but maybe you can find some long compilations (or just whole albums you can listen to start to finish) that will take up some time. Then again, one of my favorite songs from the last couple of years (Iced Earth's "Dante's Inferno") is about half a normal album's length at about 15 minutes long.
- Roleplay, maybe with your son if he's interested. Do something with him in the house (if available) to burn away the hours. Nothing like building an (modestly innocent) story out of the air, no?
- Write. Poetry, creative prose, etc. Making D&D stats is my current equivalent to writing, as my stats for Dungeon Crawl Incorporated and Baldur's Gate characters can attest to (note: current stats of these have been outsourced for the time being; I hope to eventually update you all on at least the BG stats).
