Come rain or shine!

Cool expression:
雨が降ろうが槍が降ろうが（あめがふろうがやりがふろうが）

Encountered this in some grammar studies. Basically, it is the Japanese equivalent of "come rain or shine, someone will go somewhere." But this one is a lot cooler sounding -- if translated directly it means "come rain or arrows."

According to 広辞苑, it means: どんなことがあっても。どんな困難に出会ってもやり抜けるという決意をこめた語。Most of the examples I've seen use 行く following the construction, but other action verbs are possible.

例文：　雨が降ろうが槍が降ろうが北海道に行きたいな。
例文：　雨が降ろうが槍が降ろうが列に並びたい。

There are several other variations of this construction, all with similar meanings.

雨が降ろうと槍が降ろうと
雨が降っても槍が降っても
