Why is there lipstick in Nadine's bush?

We got together again with Steve & Nadine at their house for a little detecting.
On a neighbouring property they were starting to build a barn and had dug a lot of earth and piled it in a large pile beside the property. We were detecting the piles and only finding junk metal. We ended up finding 1 penny. It was discussed we were going to go into a nearby bush that when Steve was younger would occasionally go into to play. We followed a trail and Steve & Bob went down to where there was a cave but the water was too high and they had to turn back.
Nadine & Mary were looking around and found old smashed bottles so we knew there would be a bottle dump somewhere but we never located it. We started detecting the trial and found an old Lipstick case -- strange place for that to be.

We continued down the trail but Bob started to feel shakey (lack of food) so we sent Nadine back to the house to retrieve some chips and pop while we continued detecting -- we found two horse-shoes and a pocket knife.

We continued down to the creek and Nadine caught up with us for a snack break and we continued on to another path where Steve remembered seeing pine tree's in the middle of a Maple forest, which was weird -- maybe there was a building there at some point, we didn't find anything though. It was decided we would head to a local school. There was another family playing in the playground equipment, so we headed for the baseball field / soccer field. We found some loose change in the field and a lot of pop tabs. Steve and Nadine moved to the playground equipment and came back out. It was getting dark so Bob and Mary headed to the playground equipment and collected $7.00 in Loonies (How did Steve & Nadine miss those?!)
LOL As it because too dark to detect we headed to a local pizza place and grabbed some slices and came back to our house to detect.
