I remember when my group were so close to the end of our final day of our expedition and we got to a part that was in a huge forest and our route was closed for tree cutting and so we made the executive decision to take the route next to it. LITTLE DID WE KNOW SOME FORM OF TANK HAD BEEN UP THERE EARLIER. So we started walking and it was beautiful until we came across a long uphill which had huge dug out bits where tires would of gone with walls of mud Ethier side about 3 foot tall and as we were walking along this big wall of mud one of our members jumps to the center island and walks along there for a bit then we stop to look at the map and after looking at it we started to walk off I turned around to see my teammate on the center island with his foot being sucked up by the mud we pulled his foot out but his boot was really deep so we decided to find some bark and go digging!! All worked out alright though. Made it to the end in good time.
