I tried last night to find 4 when my window opened and nothing, as I said in a previous post.
HOwever, I was playing around this morning, and first found a single. Then I found one to overlap, so I would be able to at the very least to have my son and myself. Then I found another single (#3) earlier in the day. I just found a fourth single! Almost all 4 overlap!
Check it out!
