Cal, now that sounds like a plan! As someone that has long wanted and very recently found a Mustang for myself, I can relate.
They're definitely not winter weather vehicles but you should be able to enjoy it from at least April into late November most years. I agree with you on never being able to drive it without a smile on my face, the exhaust rumble alone does that for me.
I can't wait to get mine up to NH this summer, good luck and I hope you enjoy the trip.
