To travel hopefully

In a review of a book recounting the author's attempt to replicate Robert Louis Stevenson's "Travels with a Donkey," it was reported that RLS is the one who said "To travel hopefully is a better thing than to arrive." The reviewer does not acknowledge any other attempts to replicate this trip. Dervla Murphy apparently traveled with a mule in Ethopia, not with a donkey in the Cevennes. The Austin Public Library has deaccessioned a lot of her books. The book reviewed is To Travel Hopefully (Christopher Rush). My Stevenson donkey tour shares a book with The Silverado Squatters, bought at the original Half Price Books, which shared a building with a Jack Brown dry-cleaning plant.
