Yes it is a broad question
I posted the question because I have only used a guide once. I tipped him about 20%. My expectations are not too high (at least in my estimation) I expect the guide to know where some likely locations are and make the occasional suggestions about how modify what I am doing given the location. Like some others have indicated for me the guide's attitude made the differnce in my tipping level.
I may have the chance to go out to Colorado and get some fishing in and wanted to know what others thought was the norm. I do appraciate the info provided and the variety of viewpoints especially the views posted by guides.
it is usually better to be conventionally wrong than unconventionally right
