Those sketches are awesome! WTPA's going to be great.
Oh I need to ask. Is anyone who IS going to the WTPA and owning a laptop willing to let me lend it for the day? I don't actually need to carry it, but I'm not sure how many photos I'll take and so I need somewhere to deposit the extra photos, and then burn them to a CD or preferably a DVD at the end of the day. It must have a USB port, plenty of hard drive space spare and a CD or DVD burner. 

Please alert me as soon as possible.
