We all have one. It can be many things. For many it's the fact that they are no longer smoking. For some it's that they were able to go mountain climbing, even on a famous mountain and didn't run out of breath and vaped at the top. Maybe you vaped at an exotic landmark in the world. Some got away with vaping in some crazy places. For some it can be more of a personal feat. For me it's when I started to build my own coils and then never turned back to my dusty Cloud Beast. Also in the summer I am able to do serious mountain bike riding for the months of July and August in the Catskill Mountains and couldn't do that while smoking. What's your vaping feat?
