We're thinking of rafting with this company in the beginning of August. We're a family of 4 with 2 children ages 9 and 11 and have only done "float trips". I'm a nervous mother and not a big fan of roller coasters. Do you think we (I) will be able to handle the upper pigeon raft trip with Smoky Mountain Outdoors Whitewater rafting. I see they get rave reviews.Thanks.
