Masshntr--Even though I have some friends that split the pelvis, I never have. Some professionals recommend against it since it opens up more area for contamination and causes more meat to dry out which ruins it. I have always done the reaming method, circling several times around the anus until no visible attachments are seen. After that, reach inside and tug (not too hard) on the opposite end of the rectum and look from both sides to see what's keeping it from pulling free. Cut those areas free being careful not to cut the bladder or open up any intestinal tubes. Once this is done, most of what is behind the diaphragm should easily come out.

As for splitting the brisket--there's no reason to. Split up to where the ribs meet and stop there (maybe even earlier if you're considering mounting the deer). From there you can reach up inside the cavity and feel for the windpipe which you should cut as high as possible. Everything else will pull out easily and pretty much as a unit. Using rubber gloves will make all of this less messy of course.

Saving the heart, liver, etc. can best be achieved using ziploc or even small garbage bags. Wash everything thoroughly once you get it home.

Hope this helps some.
