 #Travis traveled to Chicago and took the Clark Street #22 bus up to Dave's office. 
 #Problem:  He just left his suitcase on the bus!
 #Your task: Get it back!

 #Dave's office is located at: 
 #			latitude  =41.980262 
 #			longitude =-87.668452

 #this program monitors the identified buses and 
 #reports their current distance from Dave's office.
 #When the bus gets closer than 0.5 miles, 
 #have the program issue an alert by openning a web-page showing the bus location on a map.
 #Travis will meet the bus and get his suitcase.
