Sometimes you go ahead and do something and you really wonder if you are on track or making a costly mistake. I felt that way when I made the decision to start using lpg for gas in the family car. My wife wasn’t sure this was a great idea either. When we got back $2000 of our investment from the government grant program, we felt a little better. Every time we fill up the tank for half of what it used to cost us, we feel a lot better. I think the fact that we are not polluting our environment feels pretty good too. I Know this was the right decision after all.
