Shady Tree Bowling Alley is a Bowling Alley located on Marten Island. It is most prominently seen in mission 18 Opulence required where you have to steal back Zimos's hos which were kidnapped by Tajiri Kaneda. After the mission it could be bought by the Saints and you can play bowling here. However you are unable to play before Opulence required as the alley is guarded by Tajiri Kanedas thugs until the mission and they will turn you back and deflect your bullets with their swords. Also RPGs will not work as they will confiscate them and use them against you in the mission but only if you use one on them.
