I'd tested my SS powers yesterday from Morong, Bataan to Subic Ocean Adventure & v.v. And, I'd test it today by climbing to Timberland.
From Aling Tina's Eatery, I attacked Timberland and was able to climb it, all right, but in six stops. First stop was a mandatory stop before the infamous "siko". The second at the "siko"; the third to fifth before the next curve; and, the last after Amiya Raya. I also pedaled standing up; but, my powers were not enough to conquer Timberland on SS non-stop.
The last stop
Suman (rice cake) and Yakult at Marc's View Deck
I'll just attempt again next time with less stops.
