Real-estate, especially residential, is a good investment because we're at or near the bottom of a deep deflationary cycle in housing and if you have the money to park in it, it's likely to appreciate significantly in the long term.
U.S. bonds are also an incredibly stable investment, if you don't mind that the current inflation-adjusted rate of return is negative
or as close to it as makes no difference. The only situation in which this would turn out not to be the case would be if we get a super-conservative president and Congress that drink their own Kool-Aid and deliberately crash the dollar via debt default. However, in that situation no investment would be safe and you'd be better off stocking up on canned food and a hidey hole in the mountains.
