Plucking seldom used casinos

I have a friend who has been counting for over 10 years. He told me that if you have family members, and friends all over the country that you visit. If there is a casino there, and you only think you will play it at once 2 or 3 times a year. You should go ahead and be really aggersive, and not worry so much about catching heat. He told me he spreads 1-15 in really good shoes, leaves when the count is bad, back counts, jumps in and lays huge bets. He said when he does catch heat he just leaves, or keeps playing for a little while. He said it won't take long to catch heat, but with a good act you can really pluck this little indain casinos all over the country. I would like your thoughts on this idea.
