Keep an eye on the level, it looks to be dropping out. Also if you don't want to deal with logistics/Mike, give Aaron a call as his friends sister owns property at the put in bridge. For a few bucks Kenny, might run your shuttle and show you the put in and takeout. This run can go lower than 300 but will get easier as it drops. At 200 a strong group should get the whole thing done.
Feel free to give me a shout with any questions. 303-949-6880
ace in the hole, double down, rollin the dice, soft 7, pocket rocket, come line are a few names I would have used for these drops. Sure you'll figure em out when you go in. Be safe and the walls are undercut.
