This is an excellent way to meet hot, sexy female tourists and these tours have some lonely attractive females.
Every major city has walking or bus tours. Cities on the water usually have boat tours of some type. Check the yellow pages under "tours" to find out information on the tours. Sign up for one of the tours on the weekend.
After the tour is completed, ask her if you can take her on a personal guided tour of some unique places in the city. Being that you live there, I'm sure you can think of some great places to take her.
So why not try this method of meeting women. It's a uniquely different way of meeting women and some of the tours are very interesting. The atmosphere is great and the people are relaxed and friendly.
