Great photos eh! Glad you also enjoyed them. I would love to focus my photography on emergency medicine as well, but unfortunately there are so many emergency medicine and privacy of information acts etc out there, it would be very difficult to start things up.
I think it will always be an area that stays open for personal fulfillment and for the enjoyment and the pleasure to work with co-workers to get shots like these more than ever turning into a money making gig
I guess it would leave that much more room to take photoshoots on horses
