if you have to get some where like i do walking through marshy areas, and you dont like getting your socks and feet wet.. no matter how much i spend on boots i cant find water proof boots that really keep all water out. just take two newspaper plastic bags and put em over your socks with a big rubber band to hold em up, that way you dont cut off circulation OR dont even use a ruberband, and put that in your bootsand lace em up tight, the slightest amount of water splashed in to your boot will stay out of your socks and you will be comfortable all day long.
along with Fieldmouse's sugestions, talk to older guys... preferably older farmers in your area its easy and most of them will be more than willing to let you hunt their land or even tell you about any land that is available to hunt. its unbelievable how much information you can get from talking to the right people and some will even give you little hints and tricks to help you on your way
this one i am not so sure about it being correct i havent researched it much but it came from a reputable source, deer have yellow retinas that means tehy can see the yellow and other wave lengths that are close to that, so if you use yellow markers for distances change to a blue or purple or red. apparently they cant see those colors to well. again like i said the guy that i heard that from is a taxidermist so i have no idea if its truth or not but it kinda made sence. just like musky and walleye. they see teh yellows and shartruce (sp) colors better.
and the best advice i can give anyone would have to be "DONT EAT YELLOW SNOW!"
