Here is a stronger impression of the Lake Winnepisaukee cancel:

Having "Lake" in the name is not foolproof for rail vs steam. Oft-times you have to know the local geography or have the RPO catalogs. Here is an Inlet and Old Forge RPO, a steamboat route in New York. (As an aside this card is sent on June 20, 1928, during the 2 cent rate for private cards of April 15, 1925 to June 30, 1928, when postal cards remained at 1 cent. The card uses Scott 645 issued on May 26, 1928, leaving only 36 days of proper use on a private card at this rate - a quite scarce and underrated combination.)
