Correct a misspelling in the text and discuss the prevalence of dams in Hawaii and their maintenance requirements. Additionally, mention other problems and challenges that Hawaii is facing such as traffic barriers, high taxes, monopoly, corruption, healthcare, and obesity.
There is a mispelling here.  The corrected spelling is "The damns did us in. Hawaii had the highest percentage of damns in the country."  The Rail damn, for one.  As written: Regardless of size, structure or ownership, each dam[n] needs regular maintenance to fend off catastrophic failure. "  So, what other damns are we noted for that are as "plentiful as potholes," which damns have originated highly reportable problems such as homeless,  consistent traffic barriers around underground utility emergencies, soaring property and motor vehicle taxes without proportional matching benefits, Hawaiian Electric monopoly, police corruption, lack of doctors, rampant obesity, etc.
