I was supposed to catch a 7am flight during the crazy snow/ice storms that Portland recently endured. They were calling for freezing rain the morning I had to leave, so I called two cab companies and a town car service (two days in advance), and none of them would allow me to make a reservation. They told me to call an hour before I needed them to see if they could make it. I couldn't imagine leaving it up to chance like that.
Pros: Able to drive in snowy weather!
