Currently planning to head north from Anaheim CA to Billings to visit my niece. I am looking to travel in July or August. Currently planning a solo trip and have roughly 2 weeks to spend. Would be interested in seeing historical sites, ect as I am a History Teacher. Any advice on sites, food, lodging would be helpful. I wouldn't be opposed to going through Salt Lake but I would like a little more casual route. Looking to be conservative with my budget as fuel is high. Would like to hit some good eateries along the way if they are their and not be behind the wheel more than 4-5 hours per day as the time I spend in Billings would only be 2-3 days max. Any advice would be helpful.
