Northstar bison are reportedly usually very customer-friendly. Just ignore written rules and ask the management if an exception can be made, maybe for slightly higher cost rather than a huge one.
The main issue with froen is that the taste is less good than with nonfrozen. Also, as soon as it thaws it loses nutrients at a much faster rate, due to ice-crystals disrupting cell-membranes. Other RPDers also claim that the enzymes in raw foods slowly deteriorate until they are gone after 10 Weeks of being frozen.It`s not the end of the world, imo. My rule of thumb is to accept dietary compromises if it takes too much effort to get hold of THE BEST RPD Foods, as one can otherwise spend too much time and effort on food, thus ruining other aspects of life, leding to orthorexia. I`ll even often fast if I cannot get what I want as a bare minimum. My point is that factors such as 100% grassfed/no antiobiotics/no cooking are way more important than the prefrozen issue. That said, it is ALWAYS A good idea to spend a minimum small time each month looking for different varieties of RPD Foods and trying out different sources/supplies , as, per Instincto, one often gets tired of eating the same RPD Foods every week.Besides, the original Palaeolithic diet was far more varied than just grassfed bison:beef for example.
