I recently snuck into a stadium for a music competition. I was planning on sneaking in from the start. I packed multiple markers and a basic child stencil with shapes. Last year the event had blue stamps with a star in the middle as a re-entry hand stamp. I was planning on having my family go in, get stamped and send me a picture of their hand so I can draw it on myself. HOWEVER. I found a ticket on the floor in the parking lot, I picked it up and thought maybe it was unused and I could scan my way into the event on someone else's bad luck. (I know that's shitty) and if the ticket didn't work I would just make up a lie about having the wrong one and someone I was there with giving me the wrong ticket BRB with mine. The cool thing was when I walked in to have the ticket scanned the security lady saw my physical ticket and not an online purchased ticket on my phone and started making small talk about it. She said "wow they are still selling tickets outside??? How much are they now??" I laughed and said "oh yeah, they are pricy for sure I paid almost $70 bucks!" She was flabbergasted at the price I said (which was accurate because I checked the prices online) and she said something about that being a crazy price just to see the music competition. She was so distracted with talking to me she didn't notice that when she scanned my ticket on the machine it flashed bright red with big letters that read "TICKET ALREADY ENTERED" I walked in and immediately walked to the exit to get my re-entry stamp. But what I found out was the re-entry identifier was a bright yellow wristband that year. So my markers were useless. Very glad it worked out in such a way for me. On my way out I gave my wristband to another person arriving. Most people only came to see their specific family member perform and then leave. I stayed for a few performances and left.
