They fall in love when she caters a party for him in the middle
of Season 2 and have a very close and deep relationship until the
last episode of the season, when Monica discovers that Richard
isn't willing to have any more kids. 
Because she is sure she wants children,
Monica decides she cannot continue the relationship and they break
up. Monica describes getting over Richard as the "hardest thing
[she] ever had to do," and when they get back together in Season 3,
they decide to promptly end their new relationship before it goes
any further than sex. Dr. Burke makes a final appearance in the
last episode of Season 6, interfering with Chandler's plans to
propose to Monica, stating that he is finally willing to get
married and have children. He backs down after realizing that
Chandler is prepared to offer her the same thing, and that they are
happy together.Though he is unseen throughout the remainder of the
series, he is still mentioned often, much to Chandler's chagrin
(one prominent example featured Joey and Chandler discovering a
tape with Monica's name on it in Richard's apartment, but it was
quickly revealed that Richard had taped over the 'Monica' segment).
Monica also had a brief spell with Richard's son, Timothy, who was
also an eye doctor, but that quickly fell apart after she kissed
him and it reminded her of Richard.
Cottonwood Creek Preserve is a 220 acre wilderness area located
at the east end Cottonwood Valley Road in Wilmer. A 1.5 mile
natural surface trail follows the creek, crosses the creek via a
foot bridge and returns to starting point.
The original owners grazed cattle, farmed and grew pecan trees on
the property. They desired that part of the homestead remain as
nearly like it was in the late 1870’s and offered the land to the
County for a preserve.
The cache is a small container hidden low just off the trail.
The Friends Series
consists of 6 hidden caches along the Green Trail and the Creek
Trail. Each of the Friends will provide a clue to
the coordinates of the Bonus Cache. The
Friends Bonus Cache is an ammo box loaded with
goodies.
Richard is located along the Green
Trail and not part of the original Bonus
series.
