Hillsdale is now the headquarters for several of the Olympic shooting teams. They have 5 bunker fields and 5 International skeet facilities. As Andy pointed out there are 15 traps in the trench at a bunker facility. At $5K/trap, that's $75K just in traps at each facility. Add in computer controls, etc. etc. and you're beginning to get into real money.
The birds are thrown substantially faster than American trap birds. As a result, standard clay targets won't withstand the launching pressure, so the birds are stouter (I think the same is true for International skeet). I don't know how you could make it more difficult.
Here's info on the facility.

If any of you have youngsters who show aptitude as competitive shooters, check out Hillsdale. A conservative college which takes no federal money ( which pi**es off Washington)and as a result is never shown n any national rankings. They have won the National shooting competition about the last 6 years, and offer scholarships for shooting.
