In bug season I just have to use a tent; otherwise the mosquitoes just eat me alive!
The dog is in the tent with me, which doesn't work with a hammock.
I'm a toss-n-turn sleeper, giving equal time to back, side, and stomach sleeping, which also doesn't work.
If it's raining at cook time I can do that in the vestibule.
If it starts raining at night - as it did unexpectedly a couple of nights ago - I simply clip shut the vestibule door and am all set. I have all my gear inside, so I can also pack and get clothing sorted out before exiting the tent, leaving only the tent to strike and pack, which takes about 1.5 minutes, giving it a good shake and stuff.
