 ## Remarks
 When extending, include in your remarks, *"Extending to (Sector) (frequency), (Sector) (frequency), etc.* This will have the benefit of:  
 - Helping pilots be aware of whether or not they are in your airspace, so they are less likely to start taxiing without a clearance or traffic statement  
 - Helping pilots know which frequency to use
