First drawing is aerial view of 24 inch wide ladder, 48 feet long for riding end to end.
Second drawing is a side view of the three 16 feet sections which are 6 inches, 10 inches, and 14 inches high.
Third drawing shows simple progressive pattern of ttfs: Each 16 foot section may be crossed side to side imitating varing complexities of log ramps and edges: 1) ramp up and down; 2) ramp up, ledge down; 3) ledge up, ramp down; 4) ledge up, ledge down. One may string the different heights together: 6 inch ramp up and down, 10 inch ramp up and down, 14 inch ramp up and down; 6 inch ramp up, ledge down, 10 inch ramp up, ledge down, etc. Of course, one can mix and match

ttfs 24 inch to 6 inch overview
Seventh drawing: Drawn roughly to scale. Apparatus is approximately 130' long and 15' wide. Would add 15' on each side to ride on/off and around. Thus land area needed is 160' long x 45' wide with another 50' of length available for expansion.
Estimated cost: $758
Six teeter totters and rebar anchors will likely eat up the rest and more of a $1000 grant.
Though Chris and I looked at area along Big Papio east kiosk parking lot, I think the better location is east of the trailhead at the NE corner of the baseball parking lot. These parking lots are plowed in the winter so we use along with snow loop. Also would be available for play time during Psycowpath race.
