Surprises me that anyone would just leave one. I remember when Draysen did my son't pronghorn, I couldn't wait to get it back! (BTW, kudos to Draysen.! AMAZING work and fast service!!!)
My opinion is that the 60 day time frame he is targeting should be very reasonable! Possibly some sort of verbiage as to a penalty for not picking-up by the 60 day mark? ($1 per day storage, thereafter... ???)
