Yah if you're getting too many flats take a look at what you are doing on the road. If it's pinch flats be a bit more considerate of the rough bits if it's glass and wire don't go though the ugly stuff if you can avoid it.
Always remember that flats are part of the game too, no need to take too much effort with gear or line to avoid them they'll come anyway. I only get about one a month but occasionally lady luck takes me out behind the shed and I get 3 in a day. Nuttin to be done for it if you're city riding and can't pick your destinations.
