Wanted long leaf pine seeds

I have a very nice gas powered wood chipper/leaf shredder that can chip limbs as large as 1.5 inches. Bought it years ago from Home Depot for $675. I used it maybe 5 times and it has been just sitting in my shed for years. After all that sitting it will probably need a tune up. I am in Northern Virginia and would like to trade it for anything useful. I am interested in material to make a water feature, landscape blocks, edible plants, light fictures for my seed starting shelves, bee hive or will consider any trade offer. I don't want to ship it so you need to be within driving distance, i.e. virginia, maryland, DC, west virginia. Do you have something else you can throw in to the trade to get closer to the value of the chipper, like heating pad, large pots, worm factory, or anything?

pine seeds to trade for stenocoma -var- libani seeds

I'm a newbie and just purchased a couple of acres. I was originally thinking of doing a garden area and then having a large walk-in hoop house off to the side. However, space is a little tight (my garden plot just kept growing as I added new veggies to the plan!) and it occured to me that I could possibly combine the garden/hoophouse space. I'm thinking I could do a wood frame around the garden space and then do removable pvc/wood frames and plastic sheeting - put them on in the fall and take off/store in the spring. Do any of you more experienced gardeners have thoughts on the logistics/potential problems with this idea? Saving the space would be nice, but not if it will cause potential problems down the line. A couple of my concerns: -logistics of taking on/off the frames and plastic - would it interfere with getting cool weather crops out early/ late in the season? (ie, putting up the hoops making the cool weather crops too warm) - overworking the soil (thought I might divide out the hoop space into 3 sections where I left one bare and put compost on it in the off season, one that gets a cover crop, and one that gets planted?) - any other problems or potential issues that I'm not thinking of? Thank you for any advice!
