Elk, I've been thinking about riding with the girls and now that I have read your tried and true tips, I may give it a whirl.

Last year I bought a recumbent trike in hopes that it would offer a more stable ride for both me and my 85 lb. gsd. I didn't anticipate the trike being difficult to ride the hills, so it's parked in the garage for now. I may consider using one of the attachments on the mtb and take it out for a short spin. I like the one with the harness. As for the other attachments, unless the designer is familiar with prey drive in a herding breed, they have no idea what they are in for if a squirrel crosses the path.
