For example I have no money outside the U.S., partly because I am poor and don't have a huge net worth that foreigners would court me. ;D It's something I may try some day, but I am in no hurry. I have to admit while I see the reasoning on this, I don't trust foreign governments any more than I trust my own, which is to say not at all. I also don't see the point in geographical diversity unless you live in a locale that's conducive to immediate escape and also own a craft and have the skills to circumnavigate the world, but even then it's dodgy. Even if I did flee the US for some reason, I'd be an illegal immigrant with no rights wherever I went.
I do not subdivide the categories as Browne reccommends. All my stocks are Vanguard's Total Stock Market fund, for instance. Again, a lot of this is because I am poor and it's just too hard to meet minimums at multiple brokers, and even if that weren't the case, I value simplicity for its own sake and don't want redundant accounts and holdings. I don't bother with making sure I have everything in at least three funds in at least two brokers.
I don't bother with physical custody of gold. A major component of this is that I currently do not have a storage option due to a convoluted set of personal circumstances (sadly, I am afraid that I would be robbed by someone I should be able to trust and any workarounds would constitute hassle on my part). Also, I have serious trust issues with people who sell gold physically, they all seem to dodgy and I feel they misrepresent their product with their claims (Gold always outperforms stocks, etc.). I feel I am the most likely to come around on this one as the security issue is temporary as it has to do with my living situation, and surely there must one at least one legitimate seller.
But I would never buy that much physical gold as I'm just lazy. It just seems so much easier to buy and sell digitally.
I do not use a treasury money market for cash. Right now all cash is either I bonds or a boring old savings account. All the savings are at the same bank, not at multiple banks either.
All my bonds are in funds or ETFs not held individually.
I also have a very large Variable Portolio that's very John Bogle inspired, so half is in one strategy and half is in the other. While that's technically not a rule breaker, it's probably atypical. I feel between the methods of Browne and Bogle however I am more likely to fare better than just using one strategy or the other. So I see it as more of a strategy diversification. I figure others are likely doing much more exciting things with the Variable Portfolio so why can't mine be boring. I have other reasons but it boils down to this: I sleep better this way. If John Bogle and Harry Browne are both wrong then what chance did I ever have to begin with, eh?

I'm just curious if I'm unique in my deviations, or if anyone else breaks any of the "rules".
