First ten days of my San Antonio TX to Yellowstone WY tour --- 515 miles in Texas: San Antonio to Hobbs NM, decided to get to Yellowstone via the Plains rather than the Rocky Mountains, turned right and rode to Lubbock TX. 10 days, 515 miles.

By surreal coincidence a friend in Lubbock requested my help in driving from Lubbock TX to Great Falls MT, my intended ending point. So quite against expectations, 24 hours later, here I am in Great Falls continuing my tour going south TO Yellowstone instead of FROM the south.

Needing advice on the best way to navigate the approx. 350 miles from Great Falls to Yellowstone, specifically Old Faithful.

Tks,
Mike
