[pct-l] Umbrella with Trekking poles?

[BrianBowlsby at ieice.com (Brian Bowlsby)]

I'm considering bringing an umbrella on my thru-hike, but also prefer to use
trekking poles.
 
Has anyone figured out how to use an umbrella and still have use of trekking
poles effectively?  Is there some way I can mount the umbrella to my pack or
something?
 
I've heard that if I don't bring an umbrella, I'll wish I had. I'm just not
sure how to combine the two...
 
Any thoughts?
