Roche Harbor is a hidden little pocket on San Juan Island, with impeccably preserved turn-of-the-century buildings, picturesque lime kiln ruins, a pristine saltwater inlet, and wharf buildings that hearken back to some (perhaps slightly revisionist) halcyon era gone by. Yet I had to force myself to even look at those things, let alone sketch them—because I would have been perfectly content to spend all day staring down at my feet.
