Travis used three of them at the Stamford GC in Stamford, NY.
The 242 par 3 -1st, w/a severely downhill tee shot
The 242 yd par 3 - 3rd, w/a slightly downhill tee shot (these two holes are the same yardage, but 2 clubs difference due to terrain)
The 183 yard par 3 - 8th, slightly downhill tee shot.
They're all great fun to play, and par 'feels' like birdie.
Wyantenuck CC in Gt. Barrington has a good one - their 2nd hole, a par 3 of 246 yards. Another one where 3 feels like 2.
Orchard Creek(Paul Cowley) in Altamont NY has one on their 11th, a 165 yard downhill par 3. It's also a 3 tiered green, all sloping away from the tee.
