Place I'd like most to visit wins...
I have kind of a hard time picking just one place.... Here's a few places near the top of my list
Hawaii - My wife & I really want to visit Pearl Harbor sometime. And I'd really like to go to the Hawai'i Volcanoes National Park. (I think it'd be fantastic to see an eruption or lava flow)
Australia/New Zealand - My sister has been in Australia for the last 3 years and it really bugs me I haven't been able to visit.
Mount Sunday (the filming location for Edoras in Lord of the Rings) and Matamata (the filming location for
The Shire & Hobbiton in Lord of the Rings) are must see places for me.
Colorado - We had a Colorado honeymoon planned but we moved our wedding up because of health concerns in my wife's family. Still haven't made it there... would like to soonish. Colorado is probably the first place I'll actually make it to on my list. I'd love to go to the Rocky Mountain National Park. Maybe rent a sorta secluded cabin for a few days.
Ireland - Everything I've seen of Ireland looks incredible. I'd especially want to see the famous coastlines and a castle or two. A visit to a pub with some Irish music would be a plus. And a U2 concert in Dublin would be the icing on the cake. If I really thought about it I'm sure there would be some Game of Thrones locations I'd love to visit. I think Ireland is my #1.
