Is is easy to just 'hail' a cab? What are the odds they will be on time if we call to schedule a pick up? Will they even agree to schedule shorter routes...say a $7 or $8 dollar fare?
Relying on public transportation will sometimes leave us with arrival 30 minutes too early for our scheduled activity. If the weather is nice of course we'll walk the shorter routes, but when it is really cold and windy in the evening that is not at all appealing!
