This course has been known as the Sycamore Ridge Golf Club and more recently as The Links at Twin Towers but the name was changed to Linfield National following the September 11 2001 terrorist attacks on New York and Washington DC Linfield National is situated on rolling hilly terrain The design is very interesting in that the course is very tight with narrow fairways Bunkers play a significant part in the strategy of playing this course Trees line the perimeter of the course and are also found randomly scattered through the layout The greens are large and well maintained There are a pair of signature holes on the course Hole 10 a 393 yard par 4 has trees lining the fairway and one large tree just to the right of the fairway Heavy bunkering makes this an interesting and challenging hole The other signature hole is 18 a 460 yard par 4 which has a pond in front of the tee box that requires a carry of at least 180 yards
