Hi - I'm new to this and I also want to thank all the posters for their great and useful advice.  I have an OR 450 and (thanks to the helpful tutorials) I've successfully loaded the NY topo and MyTrails on my unit.  I was thinking that a huge advantage of these maps would be that I could mark a waypoint on the trail (such as the top of the mountain) and have the GPS tell me the trail distance to the waypoint.  however, when I've tried it, the GPS appears to give me the straightline distance instead.  I'm just using a simple method - marking the waypoint on the map.  Is there something else I need to do?  Thanks for your help.
