The weather is such a double edged sword... Rain is good, we need it. When it gets too wet though it aint much fun riding as far as im concerned. The clean up from a really wet ride is just so frustrating, spending more time cleaning and maintaining your bike than actually riding it isnt so cool. Hard ground and dust isnt always as much fun as some nice tacky moist soil but by the same token the dust isnt anywhere near as hard to clean up. Summer time versus winter time, tough call. At least you can dig and build in winter and the country looks so much nicer when its green too but summertime is so much fun still, dust and long daylight hours, mmmmm... Its all good times...
