I know Taipei is in the north. There is a good field to play at near Taoyuan (sp) http://www.falcons.com.tw/
. Paintball here isn't like in the states where you show up on any given Saturday and Sunday and there are tons of people to play. normally players play on Sundays and plan it so there is some sort of group to play with. I drive up there and play at the falcon field from time to time. There are are some field in and around Taichung to play at. There will be people playing this Sunday but not sure where yet.
