Well we just got back today and we are beat, so I will make this kinda of short. The A122 towed fine and we averaged about 16.8 mpg with the 4Runner, which was pretty good considering the mountains and my driving.
The Dry River CG was great and was very clean with large sites and clean bathrooms, our site was private and large, the other site that I would recommend is #16. If anyone needs more info. on the CG let me know. I will say this, the roads in Conn. are in bad shape and poorly designed, if your headed through the Harford area be carefull and take your time.
We hiked to the summit of Mt. Washington, which took us about 9 hours, this was a pretty good hike, so if you are thinking about doing this, you should be in pretty good shape and have some experience hiking. The weather up top is no joke, so bring proper gear and clothing. We used the Ammonoosuc Ravine trail to ascend and came back down the Jewell trail (approx. 10miles).
I would highly recommend this trip and there is plenty to see and do in the area for a family. Like I said, I am bone tired and my eyes are getting heavy as I type this, but it's a good feeling and it was a cool week to spend time with my son.
