I'd sure have welcomed something like this a couple hours ago.
After having my new quad-band mobile for a week, I reprogrammed it to put the channels I use most in the bottom section of the memories for quick, easy access (1 through 4 are simplex calling frequencies for the four bands, 5-9 are the receivers I use on a daily basis, then the 10m, 6m, 2m, and 70cm locals each have a segment of memories). I also took the time to load up (some of) the repeaters I might want to use along the route I take on my vacations to the Outer Banks -- so beyond the Piedmont area where I live and work, I programmed a stack of repeaters for Raleigh, Rocky Mount, and a couple smaller towns, then the ones actually on Hatteras and Nag's Head.
Using Chirp and RepeaterBook (plus Google Maps on my phone to verify what towns were where), it took me less than an hour to set up for continuous repeater coverage on 2m and 70cm, plus near-continuous on 6m/10m FM (some places don't have either one, most don't have both).
Only has to be done once unless something wipes the radio, and I have a backup in my laptop's hard disk, so I don't have to look up the repeaters again even then. Later, I'll dig up the cable and do the same for my HT, except I won't bother with the in-betweens, just add the ones on Hatteras and Nag's Head.
