I just returned from Vegas on Thursday at the begining of everything. We waited in line from ticket check in toour security gate checkpoint for a "D: gate. That took 2 1/2 hours. When we got to the screeners all 59 of the strikes I had were in my carry on inside a clear plastic bag.
They did set off the machine for a seperate bag check , but that was all. The TSA agent told me next time just have them out of the carry on similiar to how you do a laptop computer and everything will be fine.
Hope that helps you
