I will be doing some craft fairs and we go camping fairly often. I have researched and asked about every type of pop up canopy out there. EZ UP Encore ll so far has had the most favorable responses. I have, however, read that they can be quite flimsy and are not waterproof. I already have one that fits that bill and don't need another sunshade. Can anyone recommend a WATERPROOF one? (I do paper art and it really shouldn't get wet....) TIA
