On my very first group ride i got a puncture out in the middle of nowhere. No one on stopped to help, and why should they? I had a patch kit and CO2 cartridge, but I had run over a large screw which made two rather nasty punctures in the tube, which couldn’t be patched. After a couple hours a pickup truck with a rebel flag bumper sticker which said underneath “These Colors Don’t Run” and another which said “KKK, The Original Boyz In The Hood” stopped and gave me a ride to the nearest open bike ship (about 20 minutes away). Since then I carry a tube, a patch kit, a multitool, and a good compact pump.
