can anyone provide me with a detailed how to on casting with a fly rod? at work and don't have access to youtube...

You'll still have to see a visual to get the idea, but in general, you accelerate to a stop on the back cast, wait for the line to straighten and load the rod, then accelerate to a stop on the forward cast, let the line straighten and then lower the rod to lay the line down on the water. The movement comes from the elbow, not flicking your wrist back and forth. The best explanation I've seen is from Steve at Tightline Flyshop. 

Good explanation...the only other thing i will add is keeping the rod in the same plane throughout and the stop is the most important part of the cast and when watching a good caster, you may not even see it happen but it is there.

cool cool thanks I'll try to see a video tutorial as well

You kind of need to see a roll cast firsthand or on video, and that's what I'd call the very most basic cast.  For false casting. I generally have beginners scribe a "C" above them on an imaginary blackboard, and keep practicing until they get the rhythm.  I'm by no means an expert caster, but don't watch "A River Runs Through It,"  none of it very realistic.

Yes, that's an important point. It used to be strictly straight back and straight forward strokes to be done "right". But like others I know, I use a 3/4 arm stroke that feels more natural to me. As long as you cast on one plane (as in not swing the rod in an arc) you should be ok. 

Each rod is different too which throws another variable into the mix....i learned to cast on a medium to slow action Sage DS2 and when i got a faster action rod, I had to learn how that rod casted and adjust accordingly.

Yup, You might enjoy it, but could probably bore someone to tears going on about line weights, tapers, line length, rod specs and how they affect casting. lol The learning curve may flatten out but will never end.

oh so true....it was like a new sport to me when i got my first sinking line and then shooting line lol

I HIGHLY recommend "The Essence of Flycasting" by Mel Krieger (DVD and book).

Practice practice practice and it will become just as easy as fishing with normal tackle. Definitely not something you can pick up in a day though. Learning how to double haul is important IMO, even though you don't need to cast far distances for trout (usually), it helps shoot the line and I feel it gives me more control. You can fish in high winds if you double haul.

thanks, all this info is great stuff
