Look on the bright side - the average glider pilot probably has a far better look out than you as most of his flying is done by feel and audibly. The chances are he will have seen you long before you see him and will be thinking "I hope that p**t in the powered aircraft has seen me - I do have right of way!" but will be ready to get out of your way in case you haven't.
Yes - they are more difficult to see, but that is where proper flight planning comes in. See where gliding sites are near to your route. Come summer read the NOTAM's when the big cross country competitions are on. That way you can make yourself better prepared. It's all down to AWARENESS. Don't just look for the glider, look for the clues - sun glinting on their airframe is the biggy. Learn about what gliders do and don't need for cross country flight - that way you will have a rough idea of when they will and won't be out soaring.
