#teachuhaulmath @uhaul I wish I could teach some math to U-Haul before a class action lawsuit starts.

Since @uhaul location was about 20 miles to my house and my house to drop off is 85 miles, (not even counting stops for gas) I would need at least 105 miles. U-Haul gave me 73 and is unwilling to help adjust. I guess my loyalty means nothing to this company! Thanks!

Had a great time presenting at @CAMathCouncil north (Asilomar) - Are you smarter than AI. Best memory was when one of the participants said that one pen made no sense for BTC and was sitting right in front of @pgliljedahl. Looking forward to next year already!
