well i went to dummont in feb of this year,and it was 19 degrees at 11 am,i think that day was cold,it got up to 30 that dsy,1 of my buddys burn his motor that day,he has a 72 bore cheetha with a 4 mil on alky.i mostly ride glamis,and pismo,and the weather in those places never [in the day time]goes under 60 degrees,but ill be going to dummont like once or twice a year.as far as the shearers go i already pick up that pair of jhon,ill take a couple of pics and post them up,when ever i get them in.i dont believe that weather should effect the way pipes perform,but i did hear that once i thought i would ask you guys,just to se if anybody else has heard the same.
