No, if TDP is offline, then your contract with your fellow losers here at the 100 lb club requires that you immediately begin to use FitDay, sparkpeople, or any one of the myriad of other counting websites NO rest for the wicked!
Since we don't have internet at home, I bought FitDay for home and I love it. I too travel alot now, so I have to paper log it because I am not techno enough to have a PDA or other gadgets. Lots of times when I am traveling I just make much better choices than I used to and don't bother to log it all. For example, my usual road breakfast was 2 sausage biscuits with mayo, now I get a lean pocket or nonfat yogurt cup for the hotel room. I save lots of drive thru time and calories.
When I am home i log to my home FitDay and it really helps to keep me aware and honest about how quickly little things add up and how long it takes to exercise it off. I use it alot for weekly menu planning.
