Left the house while still dark outside and reached the Bradfield turnoff by mid-afternoon. Had enough time to stop and evaluate the San Juan bridge at Four Corners for a possible future launch site. It came up very marginal. Although the Bradfield ramp was not crowded, the parking lot was indicative of the number of boaters on the river. As mentioned on many web pages, it did indeed cost $5 per day to park at Slickrock. Mr. white pickup man patrolled the lot ensuring all were paid.
