7. Boston

Old and densely populated, Boston comes in at No. 7. It improved from the previous survey because of its increased spending on infrastructure. The bright side: Boston proper boasts a population of just over 605,000. If your children prefer their animals larger and cuter than rats, try the Franklin Park Zoo; if they want them wetter, visit the New England Aquarium.
