2 questions

for the first question someone else can probly answer better than I

for the second, I've heard they spray the fields, most folks say they've only seen spiders

I'm bringing a small can of OFF! but thats it.

I always bring some bug spray but haven't needed it.

As for dry ice, I brought some one year, but don't really remember how much in terms of weight or anything. Basically I had a couple blocks at the bottom of the cooler and regular ice on top. It worked pretty well but for me was more trouble than it was worth. That doesn't really answer your question, sorry.

try your local grocery store, thats where we got ours

5-10 lbs of dry ice would be plenty and would last the entire weekend. Can be found at your local Kroger or other grocery store.

another good idea if you aren't sure about the dry ice, is to freeze all your water bottles before you leave, they should last a few days, and you can use them as ice, we have around 30 bottles frozen.

as for the bugs they aren't too bad, but there are HUGE spiders.

Thanks for all the help. I don't have enough freezer space to freeze more than a few bottles, so I pretty much have to do dry ice.

And man...i hate spiders.

gaaaah, why'd someone have to mention spiders? *runs away*

Scary thought. lol

Black widows don't live in places like fields...you might catch them under a dead stump or in a hollowed-out tree, but they wouldn't be around the campgrounds at Bonnaroo, they like dark, damp places.

As far as recluses, they're more common in the western part of Tennessee, and they don't live in open fields, either...they, as their name would suggest, are reclusive, and they like woodpiles...that said, I looked them up, and I've never even seen one in person.

We have a really common hairy spider in the south, with a violin pattern on its back, and it's not a recluse. Its diet consists of ants and ticks and things.

Basically, you don't have anything to worry about. Those spiders are eating things you would rather not have on you (they also eat roach eggs).

we have a 5 day cooler also - but even with dry ice in it and regular ice - we had to buy 2-3 bags of ice

we only had 10 lbs of dry ice for the cooler.

plus we brought another cooler to use as a day cooler

i think we're bringing dry ice.

i'll be bringing my deep woods off. even if i don't use it, i grew way attached to it this past weekend at wakarusa where i would find a few ticks an hour if i didn't apply it liberally. my right leg and back are still covered in red bug bites from when i fell asleep not in my tent and not covered head to toe in off.
