The Bei Tou Sports Center is run by YMCA Taiwan.
They have indoor basketball courts for rent.
The fee is 300NT$ for one hour and one basket.
I hope we can gather at least 6 to 9 players to play 3-on-3 halfcourt game.
Regarding time, Saturday afternoon 1:00-3:00 PM or 2:00-4:00 PM should be fine.
The Bei Tou Sports Center is close to ShihPai station on Green or Orange MRT line.
