You would be hard pressed to find a camper or tramper who has not, at some time, suffered because of that sadly none-too-rare pest species, the snorer.
But now, snorers are officially among the most likely to raise the ire of their fellow trampers, a study on visitor experiences on the Milford Track has found.
Exploring visitor experiences, crowding perceptions and coping strategies on the Milford Track, the study grew from Doc managers' concerns about crowding on tracks.
Unsurprisingly, weather, sandflies and, strangely, bumblebees, rated as the bad points most commonly reported, among "very few negative comments".
Hut disturbances, however, were mentioned by "quite a few folk" - "especially snoring" - as well as "plastic-bag rustling and inconsiderate early morning packing-up".
Despite large groups like boy scouts and Taiwanese hikers, and issues like the use of iPod speakers and snoring, the study found nobody harboured any strong negative feelings towards others.
