Sky King-
Good idea, the slime tubes. I'm a nerd and resistant to heavy tubes. But I found a slime light tube at the LBS so bought it for the back wheel. Gonna put it on the next time I flat. It weigh double what a good road tube weighs, but what am I weenie-ing about- 50 grams.

Got tubes with removable cores- and put an extra core in my patch box. I do this already for the road bike and MTB, I don't know why I didn't do this for the commuter.

My ride today was great. Not too hot, maybe upper 80s with a slight breeze. However, there were lots of sirens right behind me as I rode- several times I looked back, they seemed to stop a block or so behind me on Desoto... Got home and found out that there was a fatal accident. It must have happened right after I passed... Gives me the chills.
