Gave Up on It
Artist's commentary
Hang in There, Kogasa-san 3863
If I buckle down, I can manage 16 hours of driving (with rest breaks, of course), so roughly 8 hours is a walk in the park. :-)
I'm heading off to Hiroshima today to take part in Touhou Yarinsai, so my next update will be after I get back. I look forward to meeting all the attendees!
