RFI New England and Appalachian Cottontails and Swamp Rabbit

Looking for any recent info or tips on seeing the three rabbits listed in the title. We will be on Cape Cod this weekend for three nights. Last week of July, we are booked for three nights in Shenandoah NP, with the rest of that trip still unplanned. Can we find App Cottontail in the Park? Where else would folks recommend? Looking for Swamp Rabbit as far north as it is “easy” to lessen our drive time. Any advice is welcome including ID and search tips. Thanks in advance. JVN
