I recently played Pocono Manor for the first time with a few other GCA members and they have a very interesting drop-shot par-three: No. 7. If I'm not mistaken, I believe that is the first William Flynn hole golfers play on the golf course.
Certainly, it wouldn't be a good situation for anyone if all the threes were like this format, but I found it to be particularly intriguing. The hole plays 77 yards from the back teeing ground, but the fun of the hole is to determine how long the hole actually plays (I think we figured it to be about 40-45 yards on the day we played it). To make it even more interesting, the greens, even this one while being tucked into a gully, were very firm and you had to take that into consideration for the tee shot too. Here are a couple of pictures that I took of the hole:
While I found Pocono Manor's drop-shot par-three quirky and fun, I find Inniscrone's very difficult and maybe a little awkward (but that could be the routing). At 114 yards, Inniscrone's drop-shot proves extremely difficult for a missed green long with a severe drop off on the back. Here is a photo taken by Joe Bausch:
I cannot put my finger on why I personally consider these holes differently, even though they are so similar in nature. And no, it's not due to my score. I've parred No. 5 at Inniscrone each time I've played it as well as No. 7 at Pocono Manor.
