Yes, it is. The aerial photo doesn't tell the tale. The distance to the green may only be 171, but it's elevated roughly 20' higher than the tee box, increasing it's effective distance. When you add the trees that block the approach from the tee (one of which is a 60' walnut tree) and the fact that the green is sloping away from the tee box, funneling toward the bunker, it becomes a "reachable" par 4. To land the ball on the green, you would have to hit an insanely long and high shot with some serious backspin to get over the trees, or would have to accurately draw the ball around the trees to put it on the green. Even then, unless you land it on the south edge, where the green flattens, you're probably looking at the ball rolling across the green and right into the sand. Most professionals would struggle to stick the ball on the green and I don't believe any would do it consistently. Even if you do, you're looking at a long birdie putt because the hole is usually somewhere on a plateau in the northwest quadrant.
To note, it actually used to be a par 3 hole back when the American Legion owned it. But when the current owner had the USGA rate the course about 10 years ago, they determined that it would be completely appropriate to change par to 4 based on there being a very low likelihood of a scratch player reaching the green in regulation due to the factors I mentioned above. They told him it could remain a high-difficulty par 3 or an easier par 4 with the recommendation being to change it to 4. The owner is a -2 handicap and when it was a par 3, he told me he only was only able to make par about 30% of the time, so he changed it to a par 4 right there on the spot.
BTW, I never said anything about me and my high handicap going for the green, I simply said left of that marker, where the second fairway area is.
EDIT: I guess if I would have remembered about all this to begin with, my original question would have been moot
