Questions to ask Robert McBurgerI would personally stick to company's guidance going forward and ask if it is time to get in based on recent guidance from CVX of year over year sales and next year sales to increase and go over $40 mil and can he give us his take on Lafarge CVX cement trial thats on going and how big can this turn into and can CVX take this result to other international cement companies ? There are so many ways to ask this question Like using CO2 as opposed to air How beneficial is it in terms of attracting customers?
