I don't live there anymore but I lived in Flag for over 13 years and it is an awesome place to enjoy the outdoors. It's a great starting spot for some great climbing, bouldering, backpacking, mtn. biking, and lots of backcountry in general. To the north you have the Grand Canyon and beyond that amazing canyoneering near the AZ-Utah Border.
As far as paddling goes it's all about the winter snowpack, so if you're an optimist then it's all good! Also many lesser known places to visit (lots of secret spots to discover too)!
