I just got back from carrying my bike home about 1 mile after just starting to go for a nice ride, I shifted into first to get up a hill, my spokes caught the derailleur and ripped it off, PWRDbyTRD tells me it's pretty typical to happen so I guess it's not a very big deal, I'm actually pretty surprised my lower end Shimano components have lasted as long as they have with the riding I do. Anyway I'll get it fixed this week and be back in business
