Wow! That is a tough day at the field.
Our club membership is getting older, we have eight guys trained in CPR, but out at the field its the luck of the draw if they are there or not. We also have a club member that is a fire department medic, that person is a great sorce of help.
Buck brings up a great point though, our sites are typicaly on the outer edge, and help takes awhile, even loger if they don't know where there going, Invite them out, let the careflight helo come on a PR flight.
We've also had guys put hands in props only to find out at that momment they are freebleeders or on blood thinners, not near at traumatic as Bucks day but still a eye opener for me.
