RE: The Rain and scent?
No expert here either, but my feeling is that after a good rain any scent you've left behind gets washed away. On the other hand, after a good rain and you enter the woods and everything's still wet I feel that the deer can pick up your scent better. I relate it to hunting dogs. They track better when the ground is wet/damp than they can with everything dry and dusty.
Just my opinion...
