During my many years on CPF a number of top people in this industry, like Mr. Bulk, Mac, Milkyspit, LedASAP, and others, suddenly vanished forever. I consider this normal, as peoples’ lives evolve and priorities change. I hope this is not the case with Dave, the best flashlight builder ever, who has uncharacteristically not responded for weeks to a direct question on this site. I do hope it is not because of any personal adversity.
