I print them off from on line, but I like doing them with a pencil:) I've found it helps me if I circle the numbers that I know for sure are where they are suppose to be, that way when I erase I don't erase those.

Somebody, dern kids I presume, had a field day Sunday night breaking into people's vehicles. My daughter's car and the SIL's two trucks were rummaged though. They only took as loose change, as far as we could see. Other vehicles around a large area had cell phones taken. Lap tops and larger items were left. So, you know it was just kids out for some fun times. No school on Monday, time on their hands. Creeps.
I do the puzzles online, but I don't use the 'how am i doing' button as that is considered cheating! :D
Certainly keeps the brain active!
