My son is a train enthusiast, so I am thinking about booking a trip to NH to ride on the cog railroad. I am trying to figure out when would be the best time to come. The autumn foliage sounds tempting, but probably very crowded time to visit, what with the appeal of leaves combined with the nearby fair. Would it be better to wait until winter, and try to combine the visit with teaching him to downhill ski? Can you learn to downhill ski in this area?
