As a Pasatiempo regular, I'll give you my perspective. We do a couple of types of aeration, one is really minimal and the greens are close to normal just a few days later. But this one is the more traditional, large hole with sand aeration. The crew works hard to make them puttable, but it's just not the same, and you'll be disappointed. Love to have you out, but it's not going to be the real Pasatiempo experience.
The club is also in the middle of transitioning a number of "out of play" areas to natural grass...all part of an effort to conserve water and return the course to its roots as a four season course, with firmer and faster playing conditions most of the year. Pretty exciting transition...the club is reducing the number of irrigated acres from 90+ to around 75, in conjunction with a new irrigation system that's going in. It takes several years for the natural grasses to take hold, so these areas look pretty bare right now, but it's going to be great to see the look of the course evolve....thanks to Jim Urbina for coming out to the club and working on the grassing plan with us.
