Group: plants vs structures

Continuing to enjoy the photos you all are adding to this group. It's fun to see everyone's interpretation of the rules as well.

It seems that many are using this for photos that are simply juxtaposing plants and structures. This is a bit off of the official rule of "any plant that is taking hold in spite of a man made structure. here, nature wins!". BUT I don't care. I'm just happy people are enjoying using the group. I will still moderate for spam and really off the topic photos, but I'm here for fun and encouragement, so let's keep the rules loose!

Thoughts?
