Do what the women here on the minn/wis boder do....Go to the Local Harley shop and simply post some posters on the bulletin board...Or have the service department give a card or poster to the female customers...
If you have a local H.O.G chapter you can meet other women there...
OR just do what I do...go for a ride and see who you meet...I have guys and gals I ride with when in off of the road...I just call and see who is free and meet them and just simply pic a direction and ride...
Too much planning can ruin a good road trip...Just simply say "that way" and see what you can see...Long trips use highway....Local trips stay on the back roads...
I prefer a hotel after 500 miles in the saddle though....You can get a long hot shower, a clean bed, and another shower in the morning to wash the sleep out of your eye...Makes for a good start on a days riding...
That is what works for me...Try it and see if it works for you...Erv
