I might add that Bunni got a kick out of Jeep drivers tipping their hands or waving at each other . See all the old cars ? Can you hear and smell the craziness ? There were lots of Harleys and motorcycles lining the streets , too .

Question: What may be the reason for strangers waving at each other ?
Answer: Because they are drunk .None of the above choices .Because of their similar interest .Because they do n't want to be cordial .
