Looking For Advice About Short Term WWOOFing in North America

Hi all, my first post here. I'm from just outside Toronto, Ontario. I have some farm property on Manitoulin Island in northern Ontario, and while i know i want to live a more self-sufficient and homesteady type life there, i'd like to do some travelling before i settle into it. So i'm thinking i'd like to travel around North America with a truck and camper, and visit small scale organic farms to see how they live and make a go of it, see what they grow, how they grow it, what animals they have etc... I'm just curious if WWOOFing farms would welcome me for shorter term stays, say up to a week or two. I wouldn't require housing, as i'd be staying in my camper, but i fully understand how farmers would prefer longer term workers who are committed to a full growing season etc, and that i might be more nuisance than contributor. I'd appreciate any input or guidance!

wwoofusa.org is a great place to find farms/communities that welcome visitors seeking experience in what the community/farm does. Most generally the wwoof'ing visits are of a day or two, to a week or several.
ic.org is a fairly good place to find a community to join for several months, to several years, to permanently. Many intentional communities also welcome very short term guests. I would look in both places for communities/farms that list what you in particular are looking for.
