<p>There are NO Metro North Railroads within what I call a comfortable walking distance from Purchase. Taking the Beeline bus service to White Plains is the easiest option, which means coordinating the schedules and can add a half hour to that time. Also weekend bus schedules are limited. My son spent a summer at Purchase and was miserable at how inaccessible it is to anything without a car, and he is quite intrepid with mass transit. The fare is $8,50 or so , train only ONE WAY, so paying for the bus adds another $4-5 bucks to the round trip cost and that fare is double. You try to get rides to the Metro north or subway or decent busline to get you into Manhattan the cheapest quickest way is what kids do. Believe me, my son is a wizard in getting around, bumming rides, mass transit, all of that, and he found it tough at Purchase to get out of there without a lot of advance planning. That killed any desire of his to go there, as excellent as their program might be, but it was not a fit for what he wanted anyways. </p>
