Couldn't agree more. I don't do a lot of surveillance but I do other activities in the field, and it always pays to have good situational awareness, and area familiarity. Just because a process serve only takes a couple of minutes doesn't mean you should skimp on the planning - knowing what's nearby, getting a feel for the area, knowing where the cop shop is if trouble flares, nearest emergency room, all that stuff that hopefully you'll never ever need, but if you do, you'll be glad you know how to get help and look after yourself when the poo hits the fan!
