We carried a platypus gravity 2 liter water filter. Worked great for 4 guys. Kept two collapsible water jugs. One for dirty water from the creek/ditch and one for clean. 40 mile dropped us 100 yards from water.
We went opening weekend 2017 and had a great trip. We went 4 for 4 on nice caribou. They dropped us in a great spot and had caribou walking through camp.
Firehole we make the trip out from Ga also. Pulling a trailer always adds another element to the adventure. You handled it well. Can only get better next year.
Exactly what Larry said. Watch them, they will travel a route. Then pick an ambush point. These guys were 70 yards from camp, care less that we were there.
