Friendly, free lessons, great for groups
Short runs, can get icy
This is my home hill(definitely not a mountain) that I've been skiing and boarding for 10+ years so may be biased. Perfect North Slopes has a monopoly on the Cincinnati/Tri-State area but it could be a lot worse.
They are very accommodating of beginners; tons of rentals, free lessons, very gentle bunny area, carpet lifts, big tubing area... PNS has always attracted the school/church/Boy Scout-type groups, even on the weekday nights don't be surprised to see multiple busses in the parking lot. There is a college night a couple times a season and some rail jams for the park rats.
There aren't many options as far as food goes-pizza, burgers, fries...-so brownbagging is suggested.
Most importantly the runs; they are short but fun. There's a good variety-from wide curvy runs, some steeps, thin glades, moguls, and two terrain parks on hill. The conditions make or break your day at PNS. One week to the next can vary widely. The staff works very hard to keep a solid base on most runs but try to go after a couple sub-freezing days. It is amazing what they can do with the snow guns and cats. What previously was a simple straight run now has 10' hills, moguls, and small tracks to jib on the sides. The other side of the coin is that when the sun sets don't be surprised by the icy crust that can form on the well-worn spots.
For the semi-experienced the trails off of Runway are by far the best on the hill with the right conditions. Deception and 'Tuff Enough are solid as well. Keep your head on a swivel on Clyde's Super Slide, it's the trail that joins both sides of the hill; the generious width and straight slope cause many to hit it too fast and human obstacles can make it really crowded really quickly.
