Last week I tested the following:
Heideweek in Ede: Uhm, nothing special there. Just another market, no special activities.
Bee-expo in Bijenhuis, Bennekom: Fun! educational. Did you know that the food they get is repsonsible if a queen is developed or that a bee becomes a 'worker'? Movie of half an hour and then a guided tour through the expo-room (about an half hour/ hour).
Bat-walk, Natuurcentrum Veluwe, Ede: Fun! educational. Did you know each bat has a different sound and that there are 16 species in the Netherlands? even a 'waterbat'?
Oud Veluwsemarkt in Barneveld; Crowded! some fun-stables, mostly standard stuff. A lot of sun and a long wait at a coffeeshop (half an hour for a cola, an ice coffee and two pieces of applepie). Merchants are wearing traditional clothes and there are some traditional trades to be seen. It will keep you occupied for an hour of three max.
Pluimveemuseum in Barneveld; eductional, fun for at least two hours. Did you know brown chickens cannot lay a white egg, but white chickens can lay white as well as brown eggs? This is not because of their feather-colours, but because of the colours of there lobes. I found it particularly fun (and cute) to hold some baby-chicks and the participation in an 'egg-auction'. Also fun on a rainy day.
Lavender-gardens in Stroe. The folder promises more then there is to be seen. This is a very young company which still has a lot to develop. You can cut your own bundle of lavender. You can drink tea in the garden. I expected some more lavender-scent there. The products are not their own, but are general 'provence' lavender products. I saw a lot of missed oppurtunities. Nice stop when on a bicycle or car-tour, but a 'maybe' visit it on 'stand-alone'bases. I would not recommend this on a rainy day.
And still two weeks of testing to go... :-)
