Cindy,
Funny you posted the memory card door, I had the same idea last night after what I was trying to photograph wasn't turning out as well as I had hoped!
I am hopefully that I will have some time after work today to give it one more shot and get my entry submitted.
You have 4 hours and 15 minutes to submit an entry! It ends at 7pm Eastern USA time. Not sure which time zone you're in. Good luck!
