River Adventure with Mystery Girl

was living in a new town and was out for a walk with my brother I think. We stopped by this park where it looked like all these girls were getting ready to play rugby and one of them was all dolled up and the other girls loved it but were surprised by it ha. Then this cute girl joined in our convo about them and james left I started chatting with her about how maybe once we matched on a app a year ago but nothing happened and we both joked about it. Then I asked her to take my hand and pull me up off the bench I was sitting on as a test to see if she really wanted me to chat with her or not. She took my hand and pulled me up. We walked down the block, the weather getting a little cloudy and maybe rain coming. Lovely chat and time, very close to the water. Then at one point had to cross this river by jumping on rocks, most of them moved so it was tough but we did it without getting too wet. Then we hugged the side of the river and walked along it best we could until we actually had to get in water. We paddled on these Little Rock raft things but then they didn't even work anymore and we had to swim under water. It was now a calm river but a more African-esque river with the threat of alligators or crocs in the water. We swam swiftly to the end where there was this really tall guy waiting, apparently a friend of ours, and he was going to boost me up and push me through this very small hole that had a NY KNICKS cover on. We tried moving it and the hole was barely bigger than a vhs player's hole. There was no way I was fitting through there so we all left and kept going and got out a different way. Alarm
