How can I connect more sensors when my lcd is blocking pin access? So, I have a lcd that takes up the whole board of an arduino mega. I want to connect a temperature sensor and make a really lame weather station, but the lcd screen is totally in the road. It's a shield so this is to be expected.

I've come up with wacky ideas, like soldering to the rear of the board but I think that's a bad idea. Surely there must be a better way? The lcd shield exposes no pins.
What you need is a shield that can go between the Arduino and the LCD shield and break out whatever connections you like.

They are generally available as "screw terminal" shields, such as this one from iTead:
