At Midvale Country Club in Rochester, RTJ's first solo design, both 9 and 18 are steeply uphill par threes. Fortunately, one is short at about 130, the other is long at about 215, so you will be guaranteed a unique approach to the finishing hole for each nine.
18 at Brook Lea (Ross) is also steeply uphill, and is actually a neat short three to finish at about 135 from the middle tees (original Ross tees), with a eight-to-ten foot-deep bunker short and right of the green. The green is steep from back to front, and is surrounded by a mini amphitheater, with old members sitting and watching the action. One could also play it at 171, but I remember the former superintendant saying he thought that, even there is a great amount of room behind the back tee, 170 was the maximum length for the hole without it becoming unplayable.
Mark Twain, previously mentioned, does have four uphill par threes, of which Seven (very short at 150ish) and eleven (very long at 230) are the best. 11 is not as steep, but is very long, and the green is a wild two-tiered affair. The two levels aren't flat either, as the green is rolled right down a mountainside.
Seven, on the other hand, is quite steep. The flag is barely visible from the tee, and, unlike the eleventh, there is no bouncing the ball on this green, as a there a deep bunker in front. The green is quite wild as I remember. These two par threes are great for a muni course, quite quirky, and this Donald Ross special with wild greens (bigger than most I've seen -- original size???) is a must play for anyone in the vicinity. In fact, it is the only thing worth doing in town!!
