Dear Ms Nadya Prasetio I am Ramesh Bitra (male) thou basically from India, now work and live in Sparta, about 100 miles from Atlanta Georgia USA. I was fortunate enough to see many tourist attractions in America both on personal level and thru package tours (to East Coast and also West Coast thru tours4fun). But Yellowstone sector is still pending on my agenda and I intend to take a similar tour as yours during end June/early July 2016. However, my trip purely depends on my off from work and its too early to say anything for atleast another 3 months. If you still possess strong desire to visit Yellowstone even till end of February/early March and comfortable enough to travel with me, suggest to keep in touch and email/message me at : rameshbitra@live.com (same ID for Facebook). Many Good Wishes and hopefully see you in Yellowstone. Ramesh Bitra.
