Absolutely agree, public transport in LA is excellent + this city favors riding a bicycle, but I would recommend to use special ones for city ( Best city bikes ). My cousin lives 5 miles away from me and I visit her mostly by bicycle, never had a problem with that.
Absolutely agree, a plumber can't be compared to a nurse. Nurses mostly deal with sick people, which are very sensitive and vulnerable, patients are mentally weaker and need special treat.
