Belive it or not, I did that in 2 days (Sat & Sun).
I brought 4 bases each day and got them signed. The Spidey Com was obviously the byotch of the bunch because it's so big. The funny thing was I had a VIP pass. It comes with a 4 day pass to the Con. Stan was there Thurs-Sun. However, I was in Europe on vacation for 5 weeks until I got home that Thurs evening. Then on the next day, my cousin got married. We are very close so I went to the ceremony and reception. That ate up all Friday. So I wasn't able to go to the Con until Saturday. On top of all that, I had to get used to a 7 hour time change from my European vacation.
In the end, it was all worth it. To be able to meet Stan and get his signature on those pieces is something I will never forget. One of the main reasons I pushed through all the exhaustion I was fighting is because I didn't know if I would ever get that opportunity again. He's 90 yrs old. I wasn't going to miss my chance. If all goes well, he'll be back in Chi-town this Aug. I'm ready for round 2. And this time, no travel plans. I plan on making all 4 days.
