After an pretty severe accident I had this weekend (lucky I'm alive) I think it would be rather prudent to have a good trauma bag around. I like the idea of something like the STOMP portable hospital kind of deal from cheaper than dirt, but I hear it has shortcomings due to price and not enough of the 'important' stuff. Where would I start after the bag itself? Or would it be better just to get the thing and add/remove as needed?
