Over the summer I was visiting with family members, (my Mom was even kind enough to make the visit a surprise for me, I didn't even know I was going until the day we left) and left without internet because they are one of the 10 people who still have Dial up.
So when I wasn't spending time with them I played a lot of video games and reread the entire wheel of time series.
What do you do when you have no internet access for a couple months?
