Half Life 2 Day 7

Today I had to scale across a bridge, but i had to walk only on girders. So it was kinda like a tightrope walk. It was long and slow. A little boring but i knew it would be worth it. Then i made it to the end of the bridge and i had to do some fighting, however it ended with me forgetting to do something at the control room and I statrted to scale the bridge to go back to the beginning. And this took me like 20 minutes to back-track and i was really frustrated. Nothing changed when i went back so i figured i needed to go back to the control room and do something. Finally when i hit the switch that i needed to, ALL of these gaurds came to fight me. But it was time to go so i had to save and leave... i can't wait to see what happens next.
