Well, I've never been to Europe either Kamala.......But I have been all over this USA, and for me , I wouldn't trade it for any foreign territory. The beauty of this country is unmatched. Do USA first and you wont regret it. Add a third week as well.
Historically, Europe is much older so it is staggering also. My BEAUTIFUL, crazy fun wife being Eastern European descent has me pointing to Prague.....Incredible. But two weeks in Europe should be spent in 1 location, maybe 2 to appreciate (or Viking Cruise) .
Now, back to the INCREDIBLE USA. Utah is AMAZING. Pass through Colorado (Legal) to get their. You will get some yellowstone in as well and TETONS ! Take a great camera with LENS. Hawaii (Oahu), was there a year and half....and I promise you, you will never find better beaches. Banzai pipeline, Sunset, North Shore, Waimeia Bay.....on and on ! Drive up California to San Fran and catch cheap ALaska airline flight to Island for a week. Come back and head north to Oregon (Legal) and Washington state (legal) along coast road....Freakin INCREDIBLE. Come back home on North passage through Wyoming and South Dakota (Mt Rushmore)...Stunning Natural Beauty.
Make up time through Nebraska, Kansas , and for damn sure MIZZOU and KAINTUCKY....(Meaning dont stop except to get a night rest) and hit DC for a tour of the Smithsonians before returning Home !
You'll never regret it, wont have to worry about terrorism and foreign lands!
After that....Have at Europe ! Praque, Barcelona, Rome, PAris !
