Polar alignment can be a tricky thing. On the northern hemisphere, we have the luck to have Polaris. But if I don't see it, it's very complicated to make the alignment.
I think the fastest way would be to use something like QHY PoleMaster or SharpCap if you have trouble to see the constellations in the sky through the polar scope. I have some marks on the ground after I had an acceptable alignment, so I just need to put the tripod on the marks and it is roughly aligned.

You're welcome :-)
