I am looking to store my car as close to the airport as possible then take a taxi, if necessary. I spend 3-4 months out of the year in northern NH. I found Public Storage that looks like it's 3 miles to the airport. On a nice day I will walk, if it's safe to do so (I travel with only a backpack so luggage isn't an issue). I will look at other storage places too but I'm wondering about taxi rates and availability. I read that taxis in Manchester charge by "zones". Is that correct and how far out does the least expensive zone go? Any advice appreciated.
