[Tfug] And another one down

[Timothy D. Lenz]

Well, I spent the extra money going with Mwave for better packing and it 
came today, wrapped in a layer of bubble wrap and stuffed in a small box 
at an angle so it would fit and a bit of popcorn added. :( At least the 
UPS didn't smash the box this time. Went out to check the mail and it 
was sitting by the front door. They don't even ring the doorbell any 
more. Just drop and run.
