Good luck.
Thermacell.... will help you with the bugs.
knife... I normally have two on me (plus a sidearm)
safety harness
flashlight...
spare release.... or make sure you have yours with you 20 times before leaving your truck
water... you will get thirsty if out there all day
small snacks... if sitting out there all day
let people know you are going and where, if something was to happen and you can't call they would know where to start looking.
oh yeah some TP is always good to have handy on all day trips.
