were differences in approach among the four: Roberts was disciplined and knew what was needed for the venture to succeed, while the laid-back Lang saw Woodstock as a new, "relaxed" way of bringing entrepreneurs together. When Lang was unable to find a site for the concert, Roberts and Rosenman, growing increasingly concerned, took to the road and eventually came up with a venue. Similar differences about financial discipline made Roberts and Rosenman wonder whether to pull the plug or to continue pumping money into the project. In April 1969, Creedence Clearwater Revival became the first act to sign a contract for the event, agreeing to play for $10,000 (equivalent to $ in ). The promoters had experienced difficulty landing big-name groups until Creedence committed to play. Creedence drummer Doug Clifford later commented: "Once Creedence signed, everyone else jumped in line and all the other big acts came on." Given their 12:30 a.m. start time and omission from the Woodstock film (at frontman John Fogerty's insistence), members have expressed bitterness over their experiences regarding the festival. Woodstock was conceived as a profit-making venture. It became a "free concert" when circumstances prevented the organizers from installing fences and ticket booths before opening day. Tickets for the three-day event cost US$18 in advance and $24 at the gate (equivalent to about $ and $ today). Ticket sales were limited to record stores in the greater New York City area, or by mail via a post office box at the Radio City Station Post Office located in Midtown Manhattan. Around 186,000 advance tickets were sold. The organizers had originally anticipated approximately 50,000 festival-goers would turn up. Selection of the venue The original venue plan was for the festival to take place in the town of Woodstock itself, possibly near the proposed recording studio site owned by Alexander Tapooz. After local residents quickly rejected that idea, Lang and Kornfeld thought they had found another possible location at the Winston Farm in Saugerties, New York. But they had misunderstood, as the landowner's attorney made clear, in a brief meeting with Roberts and Rosenman. Growing alarmed at the lack of progress, Roberts and Rosenman took over the search for a venue, and discovered the Mills Industrial Park () in the town of Wallkill, New York, which Woodstock Ventures leased for US$10,000 (equivalent to $ today) in the Spring of 1969. Town officials were assured that no more
