Drift aligning then is the easiest and most reliable. I put together a Powerpoint presentation explaining it here

You will of course need a guidescope and autoguider
I field setup each month when I go to ASNSW Wiruna. I can be drift aligned in about 20mins using PHD's graphs. I don't have a permanent mount, I have 3 stone pavers I have embedded into the ground up there that I place my tripod on. This give me a rough south pointing position, then I set my altitude scale to about 32.5deg and start my alignment routine. Usually takes about 4-5 adjustments (about 1-2mins apart) in each direction (alt-az) to get me on the mark.
