Welcome to APUG, Yong-ran!
Thanks for the great info on Holy Hill! That's pretty detailed & will come in handy for us! I have a call in to the people there to see if there are some days that might not be so good for us (with Christmas approaching, things will be hectic around there).
It would be great if you wanted to introducs yourself to everyone here. Just follow this link and select "new thread" at the top.
We're all looking forward to getting to know you better! Check the thread called "Holy Hill (Batman)!" to see get more info as we get it. Looking forward to seeing your photos!
