So, one of the best places around you would be Bear Creek Lake Park. As far as instruction, I would come out to help a few times to do some instruction. I'm not an ACA instructor though I've taught a few people.
PM me. I can venture out Sunday. Sadly, I'm injured and haven't been able to paddle for a month. I wouldn't mind doing some lake work myself.
On the river, I can abandon who I am and what I've done. However brief it lasts, while on the river I am nothing important and everything insignificant. I am flotsam, and happy to be so.
