Full of fun, excitement, romance, and nail-biting chases and disasters, the Snowden's holiday in Yellowston Park is certainly one to remember. Contending with the rough-cut mountaineer Hazekiah Hotchkiss as the driver of their coach, and teh unwelcome and rowdy Congressman and his wife from Louisiana, the Snowdens watch their family with anxiety as disaster and bad luck threated to destroy their holiday, and any chance the Judge and his wife have of a renewal of their own private passions. The two unmarried ladies of the party are willing partners in flirtation and romance to the handsome British remittance man Lord Billner and the dashing Captain Taylor.
