I've seen a few posts about this in the past, been a few years since ive been on this site. What is the land record for visiting all 30 major league ballparks in the fastest time. According to Guinness book of records, I see 29 days back in 2005. Is this still the quickest or is there something else. I thought I seen 26 days somewhere, any help on this would be appreciated. Obviously I'm not trying anything this year. Thanks again.
