Now that our friends, the Pragers, are visiting us, I think we've got the visitor itinerary down pat.

Visit KAS with a walk around Lotus Lake, ending with dinner on the deck of the Wakey, overlooking the water.
Bike on Cijin Island. (Because the Pragers are bike experts we biked from the apartment down to the harbor, took the ferry, and biked the length of the island. Not all of our visitor are bike savvy enough to be trusted biking on the streets, although bike paths are fine for general audiences.) Be sure to stop to watch the kites and fishermen, and smell the food stalls along the streets. Buying squid-on-a-stick is optional. Fruit smoothies are highly recommended.
Hike up Monkey Mountain. Monkey sightings guaranteed, or your money back. Today I did not heed my own advice to skip bringing a snack and had my bag of almonds snatched out of my hand by a very quick monkey. My scream of surprise brought both concern and laughter from the crowd nearby.
Tour the harbor area. Include the Pier 2 art installations, Banana Pier with the kite flyers, and a walk up to the former British Consulate. If time permits head back to Cijin Island and visit the bike path tunnel to the tip of the island with a walk up to the lighthouse. On the way back stop at the mango ice store. Even if mangos aren't in season the ices are one of the best foods in Taiwan and the banana ice is a decent substitute for the mango.
No visit is complete without a trip to the night market. Stinky tofu is always an option but my favorite food is the scallion pancake. We stopped for a neck massage, which makes trips to the night market even better.

We will be entertaining the third son to visit, one sister and two nieces in the next few months. Good thing the itinerary is all set.
