Packing has begun in earnest. The bookshelves are now (almost entirely) bare and I've discovered that I can fairly easily fit twelve small U-Haul boxes in my car. With a little more work I think I could get fourteen boxes in my car (without reducing visibility).
Sadly the easy part of packing is almost done. Soon the part where I have to consider if the things I'm trying to move are worth moving will begin. There should be plenty of purging (I hope hope hope). There should also be some obsessive arranging and labeling (I hope hope hope).
It seems very likely this will eat up most of August and September.
