您說得沒錯，隻看到皮劃艇，不過運河那邊倒是有那種“水上漂“。我覺得跟衝浪板差不多。

又從NPS那裏的Frequently Asked Questions裏看到有趣的問答：

What is the largest/smallest national park site?
Largest - Wrangell-St. Elias National Park and Preserve, AK - 13.2 million acres
Smallest - Thaddeus Kosciuszko National Memorial, PA - 0.02 acres

估計後者一定不在DeepCreek兄的List裏麵。
