I also just started about two months ago, and I'm always up for paddling Lyons/Boulder/Golden. Anytime after 5:30 pm is easiest for me during the week. I'm out of town this weekend, heading up to the Poudre with CWWA, something you should look into, http://coloradowhitewater.org/
. Give a holla if you want to get out next week.
Ben- Where in Boulder do you live? I'm on Mapleton and could definately swing by next time I head out if you need a ride.
