1) i'd be fine w/a shorter season, maybe around 140-something games?
2) sure, get rid of the DH, but thats what AL vs NL is all about. Being different and coming together at the end of the season to decide which League had the best team.
3) no-no's - not sure what "bring them back" means
4) all kids under 12 free - that would get families back to the ballparks, i like that idea better than the 3 above
