HOW I GEAR UP AND PREPARE
You'll find many different ideas on what gear to buy and what to bring with you, and I am not trying to pass myself off as some kind of expert, but what I bring with me is below for what it's worth (specifics in parenthesis if I can recommend the product, the company behind it and the customer service of that company).
As for purchasing things from your list, I'd go to Dollar Tree first, then get everything you can from the remaining list at Wal-Mart or a place like Dollar General or Family Dollar. After that go to a sporting goods store and, for anything that's left, go to a specialty store. This will make buying gear the most cost effective. I'd try online too, obviously, because there are some really good deals out there.
To go paddling I bring (in
no particular order):
A BOAT! (I planned a group outing once and with too much on my mind I forgot mine and had to turn back en-route!)
Long sleeve moisture wicking shirt.
Bike shorts or bathing suit
Water shoes
Paddle (I use a Bending Branches Infusion) with glow-in-the-dark stickers on it for added night visibility just in case.)
Baseball cap
Hand towel to put over my head to block sun and to get wet in the water when I want to cool off
Sunscreen
Digital camera
First aid kit with some
outdoor survival items (I use one from
Adventure
Medical Kits)
Enough trail mix for 2 days just in case.
Enough water for 2 days just in case. [Side note: I don't use sports drinks anymore. I've found that trail mix has enough electrolytes in it. Sodium and potassium are almost always found in trail mix and are probably listed on the label. I can't imagine a trail mix that doesn't have these minerals in it.]
To go hiking I bring (in no particular order):
Long sleeve t-shirt even in summer (barbs, poison ivy, ticks and sun protection are all in mind here)
Jeans even in the summer (for the same reasons)
Hiking boots
Map or guide book
Carpenter belt with plenty of compartments to put all my stuff in. [Side note: I use this instead of a backpack because I find that it keeps the core of body grounded when I wear it low around my waist. Do this, and you may feel a positive energy flow as I do. I feel as if my spine is lengthening up from my core and releasing energy. It's a surprisingly powerful feeling.]
Some kind of mesh that comes down over my face to keep out gnats and other insects.
Hand towel
Sunscreen
Enough trail mix for 2 days just in case
Enough water for 2 days just in case
Cell phone with number for the nearest outdoor recreation area or forest service.
Digital camera
Head lamp just in case I'm gone until after dark.
Extra batteries for camera and head lamp
First aid kit with some outdoor survival items (same paddler medical kit as above)
Can of some kind of pepper spray which I keep within easy reach
Pocket knife
Dog Repeller (see above)
Just me, but once I've packed up the items above I select some tunes for the ride. I'm usually in a pretty good mood because I know that I'm going to have some fun and I want some tunes that will match that mood - something that will pick me up and throw me around a little. Me, I go for contemporary rock - Anberlin, Madina Lake, Switchfoot, Sanctus Real and MXPX are favorites. When I head back I usually ride without tunes in order to let the experience sink in.
