Loud Green Man
I struggle to write in a forwards direction.I suppose the forehead rest provides a golden opportunity for birder nerds to punk their 'friends' !
I can just see it where Mr/Mrs/Miss dedicated Swaro owner puts their bins down for a few minutes to be watched over by their 'friends' - who then proceed to write 'Zeiss' or 'Leica' or 'Nikon' or something in permanent black marker on the contact surface of the rest. The first time unsuspecting Mr/Mrs/Miss puts binoculars and rest to forehead - they are indelibly 'branded' for the rest of the day !
Imagine their surprise when they get home and look in a mirror to see what everyone has been sniggerring about all day !! :-O 3
