Ketchup, you could launch at the big public ramp which is right outside of Grove. To the mouth of the Elk from there you'd have about a 5-7 mile run. I heard that it took Edwin a 1/2 hour to get to his spot from Grove. I also heard that Edwin damaged his prop on the last day up there, so watch out, lots of wood up there and it is shallow - I have not been up there myself, BTW.
This resort is on the lower Elk, they say they have a ramp you can launch at for $5. I'd call them to verify, but it would save you some time if you can launch there.

Personally, I would not go fish that spot, it is going to get hammered, plenty of other places to fish on the main lake.
