Wow got a reservation at normandy farms, it usually is booked a year in advance.
Your are close within 5miles of gillett Stadium and patriot place(shopping) they have a train their but unsure of the schedule. Boston is not far as you can go 95north and it splits go left to 95north/128 or go right to 93 south where 5/8miles up it splits again and you would bare left follow to boston. But the best way is to take 95n/128n to mass pike 90east, in my opinion.
Campgrounds there is a CG in littleton(minute man Cg) i heard was ok. You could spend sometime learning about the shot heard round the world. Or travel down rt2 to alewife T station (arlington, back in the revolutionary day called Menotomy)and take the subway in to boston. take the duck tour and the aquirium. Plenty of shopping and history the north end is an easy walk from the aquiruim. There is parking at the aquirium but it 415 or $20bucks. If you want a real rural cg pineacres in barre/oakham mass closer to worcester but really out in the woods I like it has pool resturaunt, pond. sites are good size. boston is over an hour away. (forgive my spelling and grammer doing this at work lol)
