John,
No need to call me sir, David or hey you works. W2HEF got everything except my D70 and my 50 1.4. It's no use having all this gee wiz stuff to take pictures with if I leave it at home because it's dusty over here. That's what insurance is for.
hehe , David , i am from Texas and guys always call each other "sir"
my brother was a Marine then got out for a while till the Army rang him up, sent him to DLI in San Fransisco and Ranger school, even tho he is shorter than me i definately call him sir
