life time experience in the states

#winhkflight gotten US visa for almost 19 yrs and finally I took the courage to pay this beautiful country a visit. didn't disappoint me at all. we flew to SFO and started our roadtrips down south then Nevada, Las Vegas, grand canyon is probably the most astonishing national park I've ever been. wish I would have another chance to visit the east coast again. probably winter would look wonderful
