In the scene where Clark and Kara are about to open the picture in the Kent kitchen, when the scene opens the picture in the frame is just of Martha, but as Clark picks the frame up and flips it over you can clearly see a picture of Jonathan and Martha.
When Clark learns Kara has been arrested, Lex tells him she's been taken to a lab in Virginia. The next scene opens with an aerial shot of Washington, D.C.; the unmistakable Washington Monument is visible in the background.
Correction: Washington, D.C. is outside of Virginia. Arlington, VA (where the Pentagon is located) has plenty of government and government contracting offices.

The year is supposed to be 1986, but the TV in the Kent's living room when Lara and Kara are there while they're at church, looks very 90's.
After Clark rescues Kara, they go back to Clark's house to open up the back of the picture of his earth mother Martha, however is the wrong photo in the frame (at around 7 mins).
Lara had place a portrait picture inside Martha Kent's frame in 1986. During the season 4 finale where the second meteor shower hit, the Kent house was destroyed. Clark and Kara pick up the 'undamaged' frame to see that the Lara's portrait picture is still there and in place.
