I think a automobile fee + an extra fee, if non-resident, is fair. My main concern would be that the city budget for Belle Isle would be cut by whatever revenue is generated such that BI budget would remain flat.

All in all I am happy to say that BI is in the best condition it has been in decades. The only real 'eye sores' are the zoo and some of small abandoned maintenance building on the east end of the complex. However they finally pull down the ivy and painted the main building. IMO they should demolish the zoo and return it to forest. It could also do with a major Canadian goose 'harvest.'
