Over-Engineered Walks a Year Later: randomized deck from index cards

I still let some written-on index cards figure out my walking route to work each morning. If my route doesn't bring me to the correct block, then I take the last card, cross out its number, and write in a new one. By now, most of the cards have their numbers changed.

Partly as a side effect of these new numbers, the deck's suggested route tends to meander more now. I find myself "cheating." I peek ahead at the next few cards: if the deck tells me to walk around three sides of a block, I might shortcut the meander. If the deck tells me to walk all the way around a block, I probably just stay put.
