I'm looking to switch to using a hammock full time. I usually take my dog (who will NOT sleep in the hammock with me), so I want the option to stake one side against the ground to provide her with wind blockage while still having enough width to give me rain coverage. She usually sleeps under me on a camp pad.
What size tarp should I get? I think I want a plain old rectangular tarp. I use the Grand Trunk nano which is 9' long.
