Thought I'd give an update. Got off Sunday, 8/15. Never put up a tent.
Put-in - some small annoying guys that attacked light.
Upper river - windy evening, so no problem.
Echo park - they were around, so if you plan to hang in the shade before going to get water or explore have the bug spray ready.
Mid river - yellow jackets were very interested in dinner.
Hells scout - some of our group went for the upper eddy. There is a yellow jacket nest in the tree where you'd most likely tie your line. Use the lower eddy.
Jones - a few bugs, but not bad. There are some brave skunks hanging around though.
Island park and below - can't really say as we had a breeze for the float out.
"Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover." - Mark Twain
