Tillinghast's only design in Ohio, Lakewood CC in Westlake, OH is pretty good, but most would probably find it pretty mediocre. Recent minor renovation work has spruced the course up a bit.
One you really don't hear much about on a national level is Golden Valley G&CC in Golden Valley, MN. Despite the not-so-great name, the golf course is just awesome and would be enjoyed by many on here. Really severe greens, awesomely deep and penal bunkering, and really neat fairway contouring...it's a tough but fun golf course. Currently it's on the GW "top 200" classic list.
