well it kinda depends on if Wi thumper is bring all his goons and also if you guys plan on staying here at my house, in which case i would ask my parents or if your staying in Black River falls at a hotel. I don't think it would be a problem for about 4 guys to stay here cuz we have beds for that many and i'm sure my parents wouldn't care too much. so i kinda need WI Thumper to give me a for sure that he can come up on those days and go riding. so far he said he is almost positive. BUt i need him to be certain. I'm not sure but it sounds like WIThumper plans on staying in a hotel so in that case, sure you can invite your friend because we will have plenty of room around here then. But if he and his three buddies are planning on staying over here and so do you then I could accomidate one more person(your buddy) as long as he doesn't mind sleeping on the floor. As far as what to bring, just bring your riding gear, your clothes, probly a pillow cuz we don't have too many of them and if you want you can bring a sleeping bag otherwise we have some sleepingbags and/or sheets for the beds so nothing else you need to bring. WI Thumper KEEP us posted!:) just ordered a new D733 rear tire today!:)
