Q:In ultimate spiderman pc: how can i defeat Ryno in the mission with the wet cement and the crane???
i have it for console but what you do with that is this. When he does a big slam after chasing you make sure he does it in the cement area, then go to the crane and it cutscenes to you hurting him. Then you will follow him some more to a car shop. He throws cars at you, when he does a big slam sparks from his back disappear (they were caused by the crane) jump on his back and keep smashing him till he falls on his back, then just repeat that and watch a cutscene of his defeat.
Q:What is the breeding season of cranes?
Mid-April to mid-June is breeding season for Florida Sandhill cranes lasts from December-June. For most other cranes, like those here in the midwestern U.S., the breeding season is March and April. I'm fortunate enough to live not too far from the Jasper Pulaski Fish and Wildlife Area where the Sandhill Cranes migrate every spring and fall. I always go to see this spectacular event.
Q:what is the message Do not weep, maiden, for war is kind by Stephen Crane?
Well, the poem talks about war and its aftermath. and its horrors. Look into Stephen Crane's life. Was he affected by war? Did anyone in his family go to war? Did he go to war? Did he see the war. Maybe he was in the war and is talking to someone who felt the affects of it.

Q:what is so ironic about the open boat by stephen crane?
What is ironic is nature. This is a correspondent who has covered wars etc. and now his enemy is the sea - nature. What is also ironic is that nature has no regard for class. We know people on this boat come from very distinctly different classes. And yet, the ocean threatens to kill them all, just the same. Kind of like on the Titanic. Rich and poor alike lost their lives. The answer is that nature is the ultimate foe, and when it wants to, it always wins or sure tries hard enough to win. That is what makes this story a beautiful example of American Romanticism. Pax-C
Q:how can I get rid of what looks like small crane flies in my yard and house. they seem to get in the grass?
First determine if they are hurting anything. If they are true crane flys they will go a way soon. If they are not hurting anything I would not treat them. If you want to identify exactly what they are capture some and take them to you County Extension agent and he/she will be able to tell you what they are and if they pose a danger to you and your family.
