Open your eyes- improve your scan and try not to rely on your GPS so much, that way you can spend more time looking out the window in all directions, taking in the lovely scenary. But failing that, if there are little white puffy clouds out on the fair weather days you go flying, keep a good look out as you near them even if the base of the cloud is a few thousand above you, as this is where you are most likely to find a glider.
Between thermals we would normally cruise @ 120 kts in a glass ship with water, so dont be surprised if someone overtakes you either.
