I had a very interesting time while waiting for movie tickets with my daughter, son in law and grandson tonight. Since I knew the movie was going to last 2 1/2 hours I was vapeing up a storm so I didnt have to leave during the movie. I was using my twist topped with my favorite protank and I drew a crowd...there had to be around 20 people asking questions. I was glad I had a number of little alcohol wipes as a number of people wanted to try. I was so glad that I had read up on the forums here and could answer all the questions that were asked. If I read things properly my favorite local vape shop will be very busy tomorrow.
