I was thinking of doing just that with the water. I still have to buy the right water bottle to really be able to keep track of things, but I have a thermos I can use in the mean time.
I found posting here has helped to keep me true up until now. I finding, though, that the longer I continue, the more I do the exercises just for me, because I feel good and want to continue. It’s a nice change.
Your community garden idea sounds like a good one!
