Zero gallons to the mile
Ja ja ja, das wooskies alles. I'm staying with CO2 until they pry the cartridge out of my cold dead fingers.
Or until I get screwed over by it.
One nice thing about riding bents is I carry 5-6 CO2 cartridges and two replacement tubes and a patch kit, and I run Schwalbe Marathon Plus tires. If I can't make do with that, I deserve to walk home.
I carry a pump (Topeak Speed Master Blaster) and 2 CO2 carts. w/inflator bit plus 2 tubes but skip the patch kit now since I've had trouble with the glue drying out (even if the tube was un-opened!) and the glueless patches not working well at all.
Oh, plus I carry a Park "tire boot" or two since they've saved me a couple of times when a tire has been brutally slashed by something evil on the road. I usually carry a cell phone but if I'm out in the boonies I turn it off since (when left on) it will hunt for signals and use up its battery. I turn it back on when (and if) I need it.

One tube, 2 C02, one quik stik, cell phone. People that have problems with c02 don't know how to properly use it. 2 or 3 tubes? I rarely have 3 flats in an entire season let alone on one ride. Say kevlar when you purchase tires. Or if thorns are a problem go tubeless.
My kit varies slightly, based on distance, and where I am riding. Rides in the city, I carry a frame mounted pump, a spare tube, and $3 in change. The change will allow me to treat one of our excellent transit vehicles as a SAG to get home.
Rural rides, under 25km, I carry one spare tube, over 25km and under 50km, I add a second tube, over 50km and I add a third tube. Each bike has a bag on it with a set of tire levers, and the appropriate tube. Tubes that get punctured, are repaired, in bulk, then I give the glue 24 hours to set, and pressure test the patch, if it's good, I let the air out, and repack the tube as a spare. I'll also throw in a chain breaker and some other tools on 50km+ rides.
Something else to add, is a few baby wipes in a zipper bag, then after changing a flat or re-seating a chain, you have something to get at least a partial cleanup. You can also carry a couple of pairs of disposable gloves, you can put those on to keep your hands clean while doing repair work.
Whatever the circumstances, it's a nice feeling to help someone out. Good for you.

^ Good point. You never know a stranger's pain.
Speaking of neato tricks, this is pretty sweet:
