I only have a handful of eagles. One of my more memorable was playing a round with my son who was about 10 at the time. It was a 9 hole executive style course. The first hole is about a 325 yard par 4 with no trouble. I had a good drive which left me about 80 yards away, slightly up a hill to a raised green. I took aim with a wedge and the ball came down right on line with the pin. Seeing as how it was uphill and the green was raised, I had no idea where it finished. When we got up to the green, I couldn't see the ball anywhere. I assumed I hit it a little too far and looked over the back side of the green, but... still nothing. With nowhere left to look... I decided to peek in the hole and there it was!
I've also had eagles the last 2 times I played the 14th hole at one of my local courses. It's a really short, downhill par 4 that will be played anywhere from 245 yards to 325 yards. The last 2 times I played it, the hole was playing at about 270... but with the downhill nature of the hole, it was more like 230. Both times, I drove the green (once with a hybrid, the other time with a 3 wood)... and both times, I was left with a putt of about 15-20 feet. Both putts never left the hole and dropped in.
It's nice to make an eagle now and again. I don't believe I've made an eagle on a par 5 yet. I've had 3 of them on par 4 holes... and my hole-in-one was technically an eagle, but I don't remember making one on a par 5 yet. I've had very few opportunities... maybe 2 or 3 times I've been on a par 5 green under regulation.
