Our next mission would take us up the Wailua River by kayak. We rented the boats at Wailua Kayak and Canoe, immediately adjacent to the river. We reserved two kayaks for the morning. I casually inquired as to the repercussions of not arriving back with the kayaks promptly at noon. The guys manning the rental equipment noted that no one was lined up to go out after us, and simply advised me not to get carried away. He warned us that it was mud season. We thanked him, stowed our gear, and headed down the street toward the river. At 7 AM, it was difficult to tell if the cool haze was simply the ambient moisture rising from the warming land, or if it truly threatened to rain. Hoping for the best, we jumped into our boats and headed off upriver to find out what lay in store for us.
