I think walking is alright under normal circumstances. We should be in Ubin by 8am after our sunrise shoot. But as we will hv our tripods, camera gears, water and such, this means we have additional weight to carry. So its not being fit but can we all tahan the heat after 9am? And we will definately move slowly cause we will snap snap and snap. So reaching the mangrove or Chek Jawa could be a challenging goal. So if we took the van, we will buy time and spend the morning at mangrove or Chek Jawa to take more pictures. Alternative, if we want to save money, we can just take pics around the jetty and the spice garden (takes one half hour to complete). Head back to mainland, have our makan session and chit chat and share ideas and interests. Just my two cents arh....I think Aunty me is game enough to take the challenge of walking...the most i skive and wait for you guys to collect me on the way back to jetty
