At mile 74.0, we came to the famous Mojave Road Mailbox, put there by the Friends of the Mojave Road in 1983. Inside the box is a book in which passing travelers are asked to sign, including information as to the number of people in their party, the date, and their impressions of their journey. A short distance behind the Mailbox is the less famous Frog Garden, where travelers leave frogs, of all shapes and sizes. We added our tiny rubber one to the mix.
