Thanks to everyone for the information. Looking forward to trying PD, if I fail, at least I tried and don't have to wonder.Debra.
Update from last post. I get to travel a bit both for work and pleasure. As I said, I'm a biker and enjoy getting on the bike for a weekend get away. For those trips, I can take just manual bags or the cycler as well. While taking the cycler on the bike (in a trailer) isn't the easyest, it does make it so I can sleep the night verse having to wake up every couple hours to do an exchange. For longer trips, I will have supplies sent to the hotel and take the cycler and a few supplies with me in the car. So far, I decided not to try to fly anywhere. Not in the mood to try to get through all the security stuff with manual PD bags, needles and such. Grumpy
