A trip down Rte 11 onto the Laconia Bypass (Rte 3) shouldn't be an issue.
I love the trips to Concord. Further down 393 from the DMV is the Ft Eddy Road Strip where LL Bean, Market Basket, EMS Sports, Staples etc. is located. Or head downtown and visit the capitol and many fine shops and restaurants. Check out the Concord Chamber website for more info!
