Letter Elaine wrote John Trip "in the trailer"

This lot includes a letter that Elaine wrote to "Dearest M & A" ( Mother and Aunt) mentioning that John has been away from 3 weeks the longest they have been apart. It also mentions that John had written about 40,000 words before he left about his trip in the trailer and that he can not wait to continue when he gets back. This could be the start of "Travels with Charley".
