thanks all!!!!!

just got back from my ubin trip......some questions:
1) regarding chek jawa, is it must book schedule with National Parks or some gahmen agency then can go? alone cannot go is it?
i cycle in ubin to this part which has a sign that says "One way entry to Chek Jawa" and when i see further, there's another sign that says "NO ENTRY" and then "STOP".
so, that's the only entry point to chek jawa?
2) i go to Mamam (spelling?) beach but it's not a beach.....very small.......but haven't go to Noordin beach yet (the one near the NPCC campsite).....is it very small too?
3) palau ubin supposed to have the german girl shrine....but how come i cycle there never see anything? where is it near to? i haven't cycle around the Noordin beach and the north-west part of the island yet.
also, there's supposed to be an abandoned school right? last time ubin got one school there not deserted liao.
4) a pity i never see any wild boar or red cockerel....i'll go again in the next 2 months....although when i cycle in the jungle area, i got hear several branches on the ground cracking....maybe it's the wild boar.
thanks all!
