憶騎台十一(環花東2023)
It is a nice trip to visit these routes again after several years. By a bike with a group of people, it is a new experience of cycling with a lot of people. The weather is nice, the view is awesome. 上次以單車造訪這條公路，已是快十年前的環島之旅。那年環島13人浩浩蕩蕩由南至北，經花東縱谷走玉長公路橫切海岸山脈到台11線。那是個炎熱的夏天，炙亮的陽光伴隨著鹹鹹的海風，海面粼粼的波光，好不刺眼，是說，青春的氣息，我依稀記得。 第9天從豐濱往新城，從民宿離開，大隊先行，我以自己的踩踏殿後，沿途享受這獨處的時刻。過了芭崎瞭望台已近中午。 在路上遇到簡易的攤販，一把大花傘一個板凳，賣著芭蕉，青草茶，是位老奶奶在顧攤，小聊幾句，竟然請我吃中餐，簡單的青菜與花生配白飯，是如此的美味。 老太太和老爺爺有個花園，有種香蕉，後來還有示範怎麼將香蕉炊熟，把香蕉放入一個大桶子且放入乙炔石後密封，真的很有意思。 今年剛好有停辦數年的環花東活動，沒想太多就順勢報名了，主要是想找尋可愛的老奶奶老爺爺。那時智慧型手機的功能尚未成熟，沒有拍照同時記錄地點，出發前用Google街景看了幾個可能的地點，大概記錄下可能的里程數，並不抱著太大的期望。 活動第一天抵達可能地點時，找不到門鈴，大聲呼叫了幾聲後，五分鐘後只有小黑狗來應門，吠了約十分鐘，我想真的沒有人在家吧。就留下了腰果伴手禮和紙條，離開了，繼續我的環花東之旅。 沿途風景秀麗，天氣宜人，輕踏著踏板向前，左邊是深藍的太平洋，右邊是青綠的海岸山脈作陪。 另一個原因是造訪那時應該要到三仙台，十多位夥伴當時想把我踩扁在地上，因為沒到。 第二天，基本上努力騎車，不能讓同行的夥伴等待太久，所以沒有什麼照片拉。 其中有一段個人覺得是最艱辛，那就是舞鶴台地，雖然不陡，但是騎到基本上已經沒有太多了力氣了，只能以最慢速前進。 活動結束後，在返程的遊覽車路上，約晚上九點多時，未知來電響起，想說這時候誰會打來，還是支家用電話。接起後，原來是老爺爺老奶奶的小女兒，感到非常驚喜，但很遺憾地得知老爺爺已在前一個月成了天使，真的是心揪了一下。 如果真的有想去實踐的事，就馬上規劃，著手進行，否則，一不經意，那些人事物就會被遺落了久遠，不再。 C Dao …
