You're welcome. You can tell Geoff and Maggie that Robyn sent you and he will know who it is...
Funny, none of the people who bothered me on trips were of the type you describe, Thorn. They all were interested in riding. Some were stronger/racer types, and others were like me, good, but slower riders, and some were much slower, but still good, experienced riders. What bothered me was the drinking and other weirdness (we had one trip where the wife sat on her DH's lap and did a lap dance during the orientation, when there weren't enough chairs to go around ). And the Trek trips definitely had competitiveness in riding. I hate that, but back then I wasn't confident enough to ignore it. DH and I know we like to ride slowly on a tour, to see the stuff, especially the big climbs. I made it through a 10 mile climb that is part of the Vuelta a lot of years; the only way for me to do that is to do it slowly, like 3-6 mph slowly. Somehow, the group in Spain really clicked and we rode together, a lot.
