My favorite part was walking along the city's lengths everywhere. My friend and I took the scenic route with breathtaking views of the Charles river, threatening overhanging clouds that refused to deter me. This river was nothing short of majestic and Wikipedia tells me that Charles is fed by approx. 80 streams and runs through 23 cities - that is no small feat! You can spend more bonding time with Charlie while you picnic, kayak, watch the sunset or just hang out.
