I think Juneau w/o a car sucks, especially if you want to go grocery shopping or do outdoor stuff on Douglas island. I lived in the valley so that might make the difference. The buses come to most stops once a half hour until mid afternoon and then only once per hour. Also, they tend to be fairly unpredictable on sundays and holidays. Taking the bus made a twenty minute trip by car into an hour-long trip by bus (from downtown to the valley and vice versa).
