Greene, H. 1990 December 10 La Selva Biological Station, Prov. Heredia, Costa Rica Arrived here approx 1000 hr after a weird trip. I haven't had one good night's sleep since returning from Uganda on November 18 - caused by jet lag, Claudia movin' out (a big surprise), and perhaps malaria medicine which I am still taking. Left Berkeley at 0500 hrs on the 8th, taken to San Francisco airport by Wendy Roberts for flight to San Jose. Waved goodbye to her, went inside and found out I was booked on a flight out of Oakland! No problem tho, as American Airlines had one out of SFO anyway. Arrived in San Jose on time approx 1900 hr, but my bags had missed connecting flight in Dallas and so I had to return to the airport on the 9th to get them, go through customs again, etc. Rode to airport w/ a paclmco whose cab was in constant serious danger of falling apart, shaking badly even at our very low speeds, etc. Had late morning coffee w/ Carmen Rojas. Rode out here w/ Blake Edgar and Melissa Merg friends from Berkeley. After lunch we walked through the Cantarara (full of water, saw quite a few tadpoles but no schools) and around the loop trail, but saw no herps. Deborah Clarke says that Edwin Paniagua is worried we have too many peccaries here now and they are killing the snakes. It is chilly in
