Hermit, you are so right! It is very contagious, but it's too late, you have already been bitten by the "bug"! We all know the symptoms, as we have all experienced it, too! It will start with "just one", then, "maybe one more", something different from the first one, say a cannon first, then a mortar...pretty soon your measuring powder, weighing the difference between lead, zinc, or steel projectiles, going for the best effects with your camera, going for targets with greater accuracy....yep, we all been there, and done that!
