Thanks for all the suggestions - especially SASless and Flying Lawyer
We managed to fit in most of your suggestions.
I did contact John Ryan at RyanRotors but unfortunately, fitting the duals and taking my Wife along in the Bell 47 wasn't going to work so he suggested an EC120 instead. What a dream machine !
Emergency floats were fitted so from Plymouth we were able to do Martha's Vinyard and Cape Cod. From Provincetown we were able to cut straight across the bay to Plymouth - awesome. If anyone fancies doing an amazing flight in the Boston area then I can thoroughly recommend this. John is a great guy to go flying with.
The non flying highlights included :
Cocktails in the restaurant at the top of the Prudential Tower. Excellent views, food and cocktails.
I can heartily recommend the Sam Adams Brewery tour. Its free and you get to taste some excellent beers at the end.
Cheers,
John
