Good post for one started so long ago.
It seems a lot of people here ride for different reasons. The "extra weight" and "getting laid" comments are funny though.
Getting laid isn't a problem, the extra weight? Really? Is your butt that in tune with the universe? If so, OK.
My wife has more miles and time on pillion that most folks ever achieve. It is our quality time. Time away from phones, TV, computers, work and all the other distractions of life. The kids are grown, but it is still "our" time. I know I ride a differnt machine than a lot of people here, but the "weight" is missed when it isn't there. It also has no effect on the handling. Sounds kina lame to me, especially with the level of "expertise" a lot on this forum claim.
Share a saddle. It takes more love than a bed.
