If at all possible, try to avoid Emergency Room visits to hospitals.  I know this may not apply to you at all but remember that Emergency Room visits can be expensive.  Try and call your regular doctor to see if he can take you immediately if the care needed isn’t super urgent.  Of course, if you’re uncertain don’t ponder - call 911.

Buy some band-aids, gauze, tape, antiseptic, and whatever else you want to put in your first aid kit.  You can put together several pretty cheaply. You can purchase some plastic containers pretty cheaply to store these in or just use old cigar boxes.  Place a first aid kit wherever you think you might need one.

The wife and I have a first aid kit at home, in our car, and at our cabin.  All self made with all the things we’d need in that area.  For instance, our cabin first aid kit contains some calamine lotion since we’re surrounded by woodlands.
