On clear days I can see Mt. Washington from a ridgetop my road.
Driving up Washington is fun. They have pull offs on the way down so you can let your brakes cool.
Hiking up in the summer isn't too bad, it takes about a day for the round trip. It is MUCH easier than Katahdin, the most impressive New England peak IMHO.
If you get the chance to take the cog train up, that's pretty neat too.
