trail maps for Maryland

[rock1616]

I am a new gps user and purchased a Oregon 450.  I and am looking for trail/topo maps for Maryland. There are many possibilities available here.  Any recommendations would be appreciate.

Thanks,
Robert

If you do not need routing nor shaded relief, my MD/DC topo plus jbensman's 'My Trails ...' would be a good combo.  MapSource and BaseCamp will only display one mapsets at a time - both will display concurrently on the GPSr.
