How do you keep current?

My difficulties in getting an IPC have really reminded me that it's
easier to stay current than get current again. Problem is, I don't know
how to stay current.

We don't get much IMC here, so flying approaches by myself isn't really
an option. We certainly don't get enough to get in six approaches and
holds every six months.

I used to have a regular safety pilot, but since moving, I haven't met
anyone, much less pilots to fly with. I've been paying a CFII to just
sit in the right seat, but that's expensive, and doesn't help my
confidence at all.

So...how do you stay instrument current?
